After Mechanic changed the coils,spark plugs, i drove the car for testing, every time i drive the car, the engine stall and die after 4-5 miles, then when i crank the engine,the engine start little bit and move for couple of feet then die, and i have to wait for half hour to start over and drive the car for another 5 miles,then stall and die!!

Hadi,
Sounds like you have a bad primary fuel pump. When the engine is cold, start the engine and just let it run. if it warms up & dies at 176F (I think that's about right), then it is the primary fuel pump.

There are a couple of checks....
Engine cold;
Install fuel pressure gauge on the fuel rail,
Pull the secondary fuel pump fuse
Key on
low or no fuel pressure = bad primary fuel pump
key off
replace primary fuel pump

Jerry thanks for info. i will try this tomorrow and let you know.

P.S. He told me that he removed some water from tank, I just put new injectors ,i hope its not bad now?!
the car been parking outside in Snow for long time!.
I replaced the 2 fuel pumps with AC delco last year.

Open passenger door, look on the side of the dash for the fuse panel. Separate fuse for each pump, primary & secondary.

When started cold, Both pumps work at the same time until engine temperature reaches 176F. After that, the secondary pump shuts off.

Newly replaced means nothing - aka "infant mortality". In fact, I had a new pump with a failed check valve - right out of the box. Nothing worse than assuming (just got a recent refresher lesson in that myself!!). Check functionality and forget about when it was replaced last. WHEN it was new/replaced don't mean sheeeiiittt!! Check um!

Hadi there are 2 fuses the one Feul Pump fuse is on the side panel of the passanger door it will say FP1.
The other is under the dash kick panel passanger side you need to remove the panel it will say FP2.

If you remove the FP2 fuse and your Z does not start then you will have to replace primary pump.

Like Paul said just because it's new does not mean sh!t

Ahhhh, the difference is between early & late model ZR-1's. In my 94, bot fuses are in the panel on the side of the pass door. I'll try to store that for the future. Thanks for the correction Pete.
