No parts stores around here carry fuel pressure gauges so bought a new fuel pump... plenty of pressure... shoots to the hood lol... but no start...

help?

should i try my old crank sensor to see if the new one is bad?

Have you verified that you are getting spark?

yes

maybe a partial break in one of the wires causing intermittent ignition problems. do a resistance ( ohm) check on the 2 wires and the copper shield wire from the CS plug to ICM plug.  your gonna have to peel the stuff back to get to the copper wire on the CS end.

i was reading through the service manual in the no start section and I have a question. Am i supposed to see RPM's when I'm cranking the engine? Cause Im not, I followed the chart through my problems and it said bad ECM/faulty wire in circuit 430(i think). also the green wire on the (bottom left/passenger side) on the ICM looks damaged. Is this circuit 430? Sorry I guess I could go look it up.

My volt meter was acting up so I havent been able to those wires... are they the same ones you were telling me to test?

You need to unplug the connection to the crank position sensor and check continuity to where the wires run into the left (passenger side) of the ICM.

Tried to check wires today... dont think i was doing it right... everything read 0. I probed all the connectors to the CPS connector. Im not good at the electrical part of automotive.

But I was reading another thread and decided to change the CPS again... and after a few cranks it started right up... and runs fine. Could something be making the sensor go bad, or could it just be a bad sensor. That seems to be the whole problem.

If you are getting 0 (or close to 0) ohms of resistance through that wire, that is good.  That means there are no breaks in that wire.

Its possible that you had a bad sensor, hopefully it works well for you now :thumb:

ya same issue again. anyone want a car? :gr_mad:  :cussing:  :bawling1::gr_guns:

:Raises hand: :laugh:

Seriously, why would they die? could there be a voltage problem going to them or something? As I understand theres little wires would up in there. I got the sensors at differant places but theyre made by the same company.... I dunno very frustrating.

So they have some pretty inexpesive fuel pressure checkers on ebay so Im probably going to buy one just to check cause when it wants to start its sprays lots out of the checker place but right now while its now starting its not spraying so much out. Could the fuel pressure regulator do this? It seems like a fuel issue now cause it wants to start but then wont kinda like its running out of gas. I really need to actually diagnose this tho. Payday friday.

When you pull the vacuum line off of the fuel pressure regulator, does any fuel come out of the vacuum line?  It should be dry in there.

Ok through my ghetto diagnosis its not keeping its fuel pressure after the regulator. Took the return line off let it prime and fuel squirted out the whole time. pressed the valve test the pressure at and got the same result as if the line was still hooked up. plugged the line and it squirts like it would when it starts. The regulator isnt leaking into the vaccuum lines but it doesnt seem to hold pressure? unless there is something that holds pressure after that line.
