Re: trouble starting
Have you had the battery checked lately? What exactly do you mean by "crank it once and nothing happens"? Like no click..no dash lights or anything? Explain please.

Re: trouble starting
i had a new battery recently, i mean it will turn over for as long as you hold the first key turn, and then it will start on the second

Re: trouble starting
sounds like a fuel pump priming issue.

Re: trouble starting
i can hear it prime everytime and my gauge reading seems good, if thats what you mean

Re: trouble starting
Air in the line, pressurised ok but needs to run through until fuel is getting to the injectors.

Did you fix the purple wire? My truck intermittedly will start or require a few cranks because of this ---

Re: trouble starting
I vote fuel pump issue. Not sure what you are running but if you are running a stock type/Walbro pump, it sounds like the check valve is bad and it's not holding the fuel for your next start up. When you hear it prime how long does it run before it stops? You may want to hook up a fuel pressure gauge and verify this.

Re: trouble starting
i'm betting fuel pump issues, also. I had a "new" pump do that in my Blazer from the day I put it in. I finally replaced that one when it died and it hasn't done it since. Cranks up the first time every time now.

Re: trouble starting
when i accelerate more the fuel gauge goes up and never goes down first, and when i prime it , it primes for about 5 secs
what wire?

Re: trouble starting
The purple wire that runs down to the starter solenoid. It has a tendency to get hot because it runs right near the downpipe, and the exhaust manifold. I'm betting on fuel pump/check valve. Does it hold pressure for a long while after the pump primes?

Re: trouble starting
Mine will hold pressure for a while. I never actually timed it but I'd say 30 mins to an hour at least. If the pressure drops back after a few minutes or immediately it's a check valve issue.
There are a couple different methods for the "purple wire fix" Do a search, there a few pages on it.

Re: trouble starting
soo what if it is a check valve?, does it need a new pump? and what will i not be able to do safley with the pump in its conditon?

Re: trouble starting
are you saying it wont hold pressure? I had a AFPR get hung up inside and do the same thing but I took it apart and was able to fix it. I know you just put a new FPR in and I assume it did this with the onld as well.
I'm pretty sure there is check valve on the fuel pump for the feed side that wont allow fuel to flow backwards into the tank. There is also one in the FPR that does the same for return side.
Your truck should prime and hold pressure for quite some time... if you can see it bleed off pressure or it wont hold for a while that's most likely your issue. The injectors need a lot of FP in order to fire fuel into the cylinders.

Re: trouble starting
Im not sure if it did this before because i put the gauge on when i did my regulator, and my truck has a faint gas smell somtimes when getting on it?

Re: trouble starting
when you turn the key forward, let the pump prime, and leave the key turned to the on position with out cranking it, what does the gauge do? Does it hold fuel pressure or bleed it off?

it bleeds off slowly and my datamaster is saying its running lean
