Hello all, As you might have read i have a fuel line problem, well i got that fixed and my car still isnt starting, i checked my fuel lines coming out of my fuel rail and i have fuel there but my car isnt starting untill i put some starting fluid down the throttle body and it runs untill that runs out. can someone point me into the right direction on this problem? it seems like its still a fuel problem to me anyways.

Did you fix the fuel line dilemma yet? Is the fuel pump running (dumb question but have to ask)? If the fuel filter installed backwards (there IS an arrow on it that is supposed to point in the direction of the engine)? Did you plug BOTH fuel injector harness connectors into the engine harness (front AND rear connectors on that harness there). Are the INJ fuses in the fuse panel and are they good?

whats the fuel pressure at?

Yes i fixed the lines i had the lines mixed and the fuel pump is running and priming, the fuel filer is installed right, i didnt unplug the injector harness?, and and yes the fuses are good iv replaced them.

no clue on the fuel pressure, how would i go about testing that

There are 2 4-wire connectors, one by the thermostat housing, and one by the distributor. Check to make sure they are plugged in. Those are for the injector harness (well, actually, the front one is for the injectors, and the rear one is for the cold start switch and the temp sensor, but they are in the same harness piece).

those are plugged in.

Could the pickup coil be bad in the distributor so its not telling when to pulse the injectors?

"not getting fuel to throttle body?"

Fuel will never reach the TB, if it does, something is major wrong, the fuel sprays from the injectors directly into the back of the valve, the TB and upper n middle intake only carry air.

i know this and other people know what i mean, what i mean is when i open the door i dont smell gas period...also ask me anything i can tell you what the cars doing

Gumby

you shouldn't smell gas there either, remove the coil plug, then crank, then pull a spark plug it should be wet with gas.

evilemokid94

ok, ill try this, any specific plug or just any plug? and also what if they are not wet?

Gumby

The main plug on the coil, so it can't start, if its not wet or smells of gas, no fuel.

the cars not starting anyways untill i put starting fluid in it then it dies after it runs out of fluid

im waiting for someone to reply to you so i can know what to do...i have a brand new dizzy..

He's already said it will run on starting fluid, so we can assume there isn't any fuel injection.

Is either one of the under dash panels on the passenger's side removed? If so, check down under the dash at one of the 2 large multi-wire connectors pointed towards the floor for wires that have been pushed out of the connectors, specifically a black one with a white stripe.

Also, get a test light, and hook it between the battery positive post or the alternator's battery terminal (the one with the heavy black wire on it), disconnect the FRONT 4-wire fuel injector harness connector, push the test light probe into either the GREEN or BLUE harness connector on the engine harness side (not the part for the fuel injector harness), and crank the engine. The test light should flash to show that the ECM is providing ground signals for both the green and blue terminals. If not, there is a problem in the ECM driver circuit, either with the ECM itself or in the harness.

Then, connect the test light wire to a ground source, preferably the battery negative terminal, and probe both pink wires in the engine harness at the fuel injector harness connector with the key on. If the light doesn't light, there isn't any power flowing to the fuel injectors. Under the passenger's side of the dash, there is a 12-14 wire connector that is clear on one side and black on the other, and a 6-wire connector that is gray (I'll check on this, but I'm pretty sure it's gray, and it will have 2 pink wires in it at the very least) that is running into the same harness as the larger connector. Make sure that the 6-wire connector is connected, as the fuel injector power runs through here. Other than that, make sure that the ground wires at the back of both cylinder heads (yes, on the distributor end of the engine) are firmly bolted to the heads.

Gumby

I know that but its better then him sticking his nose in the TB to try n suck some fumes, if he wants a sure fire sign of gas, that will do it.

still won't show if has good fuel PSI

But he wants to see gas, that will show gas if there is any.

ill do this tomorrow once i wake up...also if it helps at all today when cranking i started to get some smoke from next to my dizzy, i got back there and checked everything and didnt see any wires that were bad or any touching wires, the most i saw was a couple leafs... it only did it twice and wont do it anymore

evilemokid94

checked the connectors under the passenger side, everything is tight and plugged in there, no loose or missing wires.

iTrader: (6)

checked the grounds, they are in good shape and are tight, re checked the 4 pin connector at the back of the engine and its good, im about to test the front connector when i can get someone to crank the engine over for me so i can watch the light.

got the car running!!!!!!!!!you'll never guess what was wrong, the fuel regulater vacum hose that runs to the TB was melted shut so i didnt have any fuel running to anything, fixed that line and hit the key and she started right up!!!! i have a few vac leaks so shes running rough but running

RSFreak

Sorry to bring this post back from the dead, but my car is doing the same thing and I'm not sure I understand what you fixed. "fuel regulater vacum hose that runs to the TB" is not a part I'm familiar with.

TomP

If you look at your engine from the top, you'll see, at the back of the throttle body (also known as TB, it's the metal piece that your air intake hose and the gas pedal linkage connects to), a black rectangle (vacuum block) with hard plastic tubes (vacuum lines) coming out of it. One will curl under the plenum (metal spider with "2.8 fuel injection" stamped on it) and go to a circular part with screws all around the edge. The circular part is the fuel pressure regulator. Follow the hard plastic tubes all the way backwards from the pressure regulator around the engine and look for any that are cracked/melted/disconnected.

If one is cracked or melted you can patch it up with new vacuum hose (sometimes sold as windshield washer hose).

RSFreak

We fixed it today. It turned out to be a blown injector fuse! Only one bank was firing so it would hickup and run like crap or not start at all. We tested everything else we could think of before finally checking the fuses!

TomP

Hey that's cool you got it fixed- at least it wasn't an expensive part! Thanks too for letting us know what the problem was (in case any of us have that happen).

Project 3.4 Camaro

Btw if that vacuum hose melted it probably got too close to the EGR pipe, try to make sure it isn't/won't come in contact with it. Also, smoke at the back of the engine is most likely oil leaking out at the distributor and burning off(been there), dizzy should have an O-ring on it when installed, also should be clamped down with the metal piece that kind of looks like a bird talon or something, it bolts down the dizzy.

im not getting any more smoke, also it over heated because right under the butterfly we have to hoses that pull antifreeze through the TB, one was sealed shut so over half that side of the engine melted but i have fixed most of it

RSFreak

I no longer have an EGR valve (or any other emissions equipment) or TB coolant lines.

Project 3.4 Camaro

Bleh, I would love to remove my EGR...I probably will once I get past emissions and have the ability to shut off the ecm code.

squeakers

im getting fuel to the fuel rail but its not starting. i recently had to change out my ecm that went out and couldnt figure why it wouldnt start. Finally i replaced the dizzy then it got spark but still wont run. maybe the dizzy needs fine tuning? 1992 f150 4.9L

Hi squeakers, this website is dedicated exclusively to 1982 through 1992 Chevy Camaro and Pontiac Firebird cars , with no other discussions of different brands/types of vehicles allowed. As such, it'd be best for you to find a Ford truck forum to ask your question since it's not all that likely that anyone here is gonna know your F150 in the kind of depth required to give you meaningful help.

I wish you well on your journey and if ya ever do buy a GM third gen F body car, come on back........
