Well I changed my fuel pump, brand new walbro 255 and a new fuel pressure regulator. I have 41 psi primed and it dosnt bleed off for about a half hour. Anything else i can replace to get this thing to fire up faster?

 

What brand is the AFPR?

Have you checked the coolant temp sensor, to be sure its telling the PCM the correct engine temperature when you are trying to start it?

 

Its not adjustable, its an auto zone replacement . I have a new coolant temp sensor I'll throw that in today and see what happens. Ever since I got my computer tuned by pcmforless my idle has been lower too?

 

Put the new coolant temp sensor in and its still hard start? Maybe I just need a rebuild? It does have 145,000 miles on it now and about 30 bottle of nitrous through it.

 

It is just a case of taking a few extra cranks of the engine to start it?

 

exactly. It used to fire up with just a bump of the key, now it needs to turn over probly 5 times

 

Does it start faster if you hold the accel pedal on the floor when you crank it?

What is the dash volt meter showing when the starter is cranking?

 

im having the same problem. when i crank the car and accel it starts a little faster. Should i get a new fuel pump and FPR too? not trying to thread jack btw.
