1990 olds 98 suddenly dies. starter spray into inj. cover starts it but then immediately dies again. fuel pump and cannister filter ok. new module filter off inj. line under hood. still won't start. w

You cant check fuel pressure that way. You have to connect a fuel pressure guage to the fuel rail at the schrader valve. It should have 30-40psi when ignition is turned on. Injectors not functioning properly will cause a misfire Sounds like a fuel pump or fuel going out.

Fuel pump pulsing when i turn key on

Well the pump would not be able to flood the engine unless the pressure regulator failed or one of the injectors was stuck open.
Have you checked the regulator and injectors ? The pump relay should power the pump for 3 seconds when you turn the key switch on, and you should have around 40psi of fuel pressure in the injector line.

1999 pathfinder won't start

The basic story here is you have fuel pressure at the injectors but not going thru the injectors.
So the next question would be, do you have voltage on one side of the injectors and a ground pulse on the other side from the computer ?

I have a LS400 Lexus thats will start then immediately dies, I've checked fuel pressure and have 40psi, it is not pulling any codes, has new battery, any suggestions?


Does the vehicle rev up to about 2k RPM and then die? Does it do this every time, meaning can you start the vehicle every time but then dies?
Was there any other things happening before or several different things? Example - black smoke out tail pipe, would not hold a steady speed and jerked or hesitated? If you answered yes to these questions it is a good chance the vehicle computer needs replacing. (I had the same issue, different vehicle).

If not, do you have any more information?

I hope this helps!!!

No start

Okay, lets start with fuses, check all your fuses, then move on to scanning the computer for any stored codes, like pcm codes as chrysler has had computer problems, and make sure power wire from battery to fuse/ relay box is good and clean, then check your auto shut down relay maybe swap with a known good one, then last dis connect all injectors and check for a shorted one.

Having problems with my 1998 Saab 900 se turbo, the car would not start i thought it was due to the cold so I put the car in the garage next day the car started the next day the car started, Drove it and...

Based on the information you have provided your problem is one of two things
1.Bad fuel pump -to check this have the fuel pressure tested if above 40psi you should be able to start the vehicle. (you can borrow/rent a fuel pressure tester at an auto parts store)
2.Bad crank and cam sensors -these are what tell the injectors to fire, so if you have good fuel pressure to the injectors but still no start I would replace both the crank and cam sensors.

1995 camaro fuel pressure

With the key ON engine OFF K.O.E.O. (cycle the key ON-OFF several times as pump only runs for 2 seconds) the pressure should be 41-47 PSI

Won't start

Spray starter fuid or brake fluid in the intake, If the car starts I would check each injector for pulse, then you can start looking at the pmc for problems,
How is the compression in each cyl ? I have did this myself, (washed out the cyl) put some motor oil in cyl. and replace plugs ,then try to start.
good luck I hope this helps.
