No start after adjusting timing and replacing fuel pump

shorty · Oct 22, 2013

put a walbro 255 pump in. car drove like poo afterwards, hardly any power and had a slight miss.
took the car back home, i knew my timing had been a little off for awhile after replacing the upper and lower gaskets, so i added a little timing. car still ran like crap miss had got worse, came back home parked the car.
Went out yesterday morning and now the car will not start.
I checked spark which is good. as far as fuel as fuel pressure goes" i have yet to hook up a pressure gauge but i removed my fuel line that goes to my nitrous solenoid and it had plenty of pressure and fuel.
sprayed carb cleaner in and the car started for a few seconds
I plan on going and renting a pressure tester when i get off work.

Just looking for ideas on what else i can check.
Maybe jumped timing?
i put my timing back down to where it was. still didn't fix it

When you turn the key into the on position can you hear the fuel pump? It may be a dead pump causing the issues

yea, i can hear it pretty well.
even when i disconnect my fuel line and let all the pressure out, then hook it back up and prime the pump. I can go back and remove the fuel line again there is fuel and pressure back in the line.

What about the neutral safety switch in the trunk, was that messed with at all?

didnt know a 5 speed had one of those.
I know the fuel pump relay safety switch is not popped up.

Your not getting fuel to the engine is my guess as to why your having so many issues. Check the ns switch, make sure your lines are all hooked up correctly, just double check everything fuel related to make sure everything is hooked up properly

you probably connected the lines backwards lol

If the inertia sw was popped then the FP wouldn't run at all.

What exactly is the timing set at? Was the PIP removed when setting it?

Did you replace the fuel filter when you replaced the pump.

You can't remove the pip for timing purposes. .;-)
I would guess you missed something while replacing pump

Ran perfect before fuel pump was replaced?

Sorry guys been a little busy with the kids and Halloween crap.
1. fuel lines where never removed. i was able to get under the car and wiggle the pump out of the tank with out having to remove the lines.
2. car ran great before the pump swap.
3. i never removed the dizzy, but i did adjust the timing and i put it back to where it was before i adjusted it the 1st time. I just bought a light last night just waiting to get some time to go back and check it.
4. i dropped the tank and removed the fuel pump once more just to make sure everything was connected correctly.
5. the filter was replaced at the begging of summer. ( maybe its time to replace again )
so with all that being said. I have spark, and i have fuel coming into the fuel rails, so my only thought is, something is causing the injectors to not fire. i read up on the PIP device, im going to go buy a noid light tonight to hook into one of the injector harness's to see if its getting power.
If the injectors are firing, then i have no damn clue what else it could be

is it possible the pump just isn't sending enough pressure? i would think even if the injectors where getting a little bit of fuel, the car would at least start for a little bit.
Or maybe its to much pressure and its locking the injectors, but then again you would think some fuel would make it threw and start the car.

what year is it?

I would guess 94-95 since that's what tech he posted in?

yea its a 94 5.0

Timing without a light is just guessing, definitely time it right. I think CC'S95GT meant spout, not PIP. Spout needs to be removed while doing the timing.

If you didn't drop the tank to do this, do you think that you maybe kinked a line? A pressure gauge will tell you that for sure. Just make sure you get the pressure reading when the car is running.

because maybe he posted in wrong section by chance? you must be a smart ass for me making sure, because if it is 96 up can be different things? excuse me for making sure and trying to help....

So, you did pump, car did not start after that I get but did you move timing before trying to start car the FIRST time? if the car ran then you did the pump, then it did not run and you didn't change ANYTHING else, then the timing is not the reason, besides you have to move timing a ton for it not to run at all....

Does the car have antitheft? sounds like anti theft type of issue if it will run on starting fluid and not on own, hence the reason I was making sure it was not 96 up....

I would not do anything else until you get e mechanical pressure gauge...

hmm wrong section? isnt this 94-95 specific?
as far as the timing goes. i have lines marked on my dizzy and block for 10 deg, and 14 deg. ( do it for drag racing purposes ) and yea i know about the spout. so if my timing is off, its not going to be by much. but that's not saying timing isn't my problem. but hell in order to even check it, i have to have the car running. i did fire up when we sprayed carb cleaner in it. but i believe the PIP controls the firing of the injectors.

Again just making sure the years were right... I still say timing has nothing to do with it since it ran before.....
