yep no crank sensor... thats OBD2 only.

Interesting kyle... the last time i had a fuel pump die on me I was driving home with my foot to the floor in second gear trying to maintain 3000 RPM and 30 mph.

Did you check your fuel filter, as well?

Yeah, well, mine wasn't dead - but it would take MINUTES of cranking to get a few sputters and then have it barely sputter to life...and then it was fine! - so it was near dead, for sure.

no I forgot about that lol.... but all these things are making me think it can't be fuel related. Although could be weak through entire rpm and I wouldn't know since I have only had this car for a week? But I would think it would stutter alot and it isn't

[MP81]

Have you tried giving it gas when starting?

[my95z28]

didn't think that did anything as far as more fuel, thought it just opened butterfly valve more?

you're running yourself in circles here, so many things could be wrong. just get it scanned and nail down the problem.

[my95z28]

can't scan it right now, have to have a dealership do it, and even if i do it could come back as an o2 sensor running lean, WTF does that mean. Most people on this forum have more experiance than me, and as long as they are willing to help I will ask for it

From what you are describing, it still sounds like a fuel pump...

I had a 94 LT1, when i got it it first, i would have to crank it over twice to get it to start. Once it was running, it ran great, full power up to redline. Then one time when i was kind of low on fuel (like 1/5th of a tank of gas left) it died.

Replaced the pump (trap door of course) and then it would fire up instantly.

hope that helps

and also, it did not throw any codes

[my95z28]

yes it helps because on the test drive we almost ran out of gas, but no it isn't what i wanted to hear

[badinfluence]

could be other things though, in my case it was the pump.

Its a piece of cake to change the pump, just cut the trunk deck

didn't think that did anything as far as more fuel, thought it just opened butterfly valve more?

holding the pedal to the floor while cranking tells the PCM on many EFI cars to go into "clear flood mode" and may or may not help.

either way, definitely replace the fuel filter pronto, and if that doesnt help... id say were still on the track of the pump.

I remember when I changed my filter, before doing the pump - the gas that came out of the line (from the tank) was silver.

i have been having a similar prpoblem with my 96. and been chasing my tail running in circles trying to find the problem..

new plugs, wires, Throttle position sensor, crank position sensor, fuel filter, and the list goes on...


finally broke down and bought a fuel pressure tester, ( didn't want to cause i have one at home..) and poof.. no pressure.. at all.. im talking the needle doesn't even move.. so i bought a new pump and hopefully thats it.


youd be better off just testing the fuel, and seeing what it is.. it soudns alot like my car, only mine won't idle, and has no power past 3 k. so prolly not as advanced as mine..

hope this all helps!

Check engine scanned today, sticky EGR. That's going bye bye as soon as I work this problem out anyway. Fuel pump appears to be working fine as I can hear it. Could it be my fuel pressure regulator? Fuel pump could be pumping fine, but it won't hold pressure in the rail?
