well check it at the valve. if you have pressure there then your problem is in that area.

If you have a gauge on the rails what does it read?..I have a gauge directly off the schrader valve..that is prior to the regulator so that should read what the fuel pump is feeding through the lines..

Gage on rails reads "zero"or just above that.

Like Steve said. Now check the shrader valve. If you have pressure there but not on the rail, its probably gonna be the regulator.

Lol whatever it takes.. Dream was quoting himself!!! Inside joke..

---------- Post added at 09:21 AM ---------- Previous post was at 09:18 AM ----------

It sure sounds like the regulator if the gauge is at zero and the pump is working.. But you will know as soon as you check your shreader valve

---------- Post added at 09:22 AM ---------- Previous post was at 09:21 AM ----------

Schrader**

when you turn the key forward the pump will run for 2 seconds then shut off until you go to start the car. the relay get the signal from the ecu via the tfi module. now i dont know what controls the 2 second prime but i would think its possible like the guys said.

Yea the pump has to prime when u first turn the key over. It will not stay running. It just does it to keep the pressure up on start up. Take the line lose at the regulator and turn the switch over like ur cranking it and see if it pumps has out of the line. If so then unhook the other side of the regulator and see of its punching threw it if so then it's gonna be in the rails or the actual injectors

---------- Post added at 06:33 PM ---------- Previous post was at 06:33 PM ----------

I mean gas

---------- Post added at 06:35 PM ---------- Previous post was at 06:33 PM ----------

I mean pushing not punching (damn IPhones)

I wonder if its the tfi module? Test that and see if its good. If its bad your pump will still prime. But the tfi sends signal to the ecu to run the pump. Don't just change it though. You need to do some testing.

It's on the distributor. Some people call it ignition module.there should be a testing procedure in your Haynes/chilton. Now this is just a guess, so make sure you test it.

If you take it off you should be able to take it to advance and they can test it if you can't. I think it's 2 5/16 screws holding it to the distributor then once those are out slide it down. Don't just unbolt it and try to pull it straight away from the dist. It has 3 little prongs that slide up into the dist.

Ok. Let's recap. You changed pump and relay?

Did you check fuel pressure? If so what you got?

Is it firing? Is the pump running? Do you have 12 volts at the pump?

---------- Post added at 08:24 AM ---------- Previous post was at 08:23 AM ----------

Also check the pip/hall sensor

If I may start from beginning.....
Was driving car night before indy 500, left a buddies house to go to other. On the way car ran good, then I look at tach(both) stock, and 5". The needle was bouncing around,going up and down while car was driving. Got to next place it was dead. As we were leaving got a jump start ran for one block stopped.towed home.(figured alternator). Took alternator had checked they said bad, put new one on. Would not start after.thats when everybody said fuel pump. Now here we are. Not sure if anything from alternator caused? What causes tach to jump like that?

When I get home I will do some research. The tac is hooked somewhere into the ignition system, maybe coil ground.
