Could be any number of things really. Could even be something as simple as an earthing problem. Try getting a jumper lead and run it from the inlet to a strut tower and another from the earth terminal to the inlet.
I had this issue a few months back. Had poor earth to the motor so if and when it started it only run on 1 or 2 cylinders. Overcranking the motor trying to start it also fouled the plugs. I added two earth leads and a new set of plugs and never looked back now.

I'm suprised no one has mentioned this yet, I know you said you have a blank key(no chip) but does the car have a brant or an after market immobiliser ?

No.. it's completely stock.. No immobiliser at all...

I vote the fuel pump is fucked.

Ok, we'll like most people have said. You have spark and ou seem to have fuel supply, but I'd hook up a fuel pressure gauge

Fuel pump presure should be 43 PSI??

My gauge only goes to 36....

I have seen carby cars were 2 PSI was the diffrence between a working pump and starting engine...

And a pump that did somthing.. but not enough.. (engine didn't continue after starting..)

I will be puting the gauge in soon..


Thanks for all the help everyone!!! You all rock!!

OK.. i thnk we are getting some were!!

put fuel preasue gague in... I just cut the hose. Cos i thought there would be some preasure still in it. But there was none..

So that didn't sound like i good start.

Put gague in, Turn key, can hear pump and relays... No preasure on gauge...

Start motor... No preasure while turning over... So i'm thinking people who said fuel pump.. might be right!! If the fuel reg on the fuel rail had gone... would that give me the same thing?

Also if i unplug the fuel pump harness and stick my multimeter in there.. if i get 12V i presume the fuel relay is ok??

Well i have a walbro fuel pump on order... i guess its going in the coupe for now!!

Thanks everyone.. i'll let you know how it all goes..

d.

relay is fine if you can hear the pump priming

What pipe did ya cut?

The fuel line from filter... to manifold.. I'm sure that's fuel into the injectors...

It's not the return line... as that doesn't go to the fuel filter....
