Starts but won't run
Totally confused about this one. Turn the key, the engine starts, then instantly dies. Fuel pressure is good Spark is good Timing is good Anyone have any ideas, I don't care how far left field they are. I'm scratching my head over this 88 JDM S/C

Check the close circuit relay and the air flow meter. Both have circuits that if they are not closing, will turn off the fuel pump as soon as the starter is switched off. Easy way to test is to jumper the FP to B+ terminals in the Diagnostic box. If it starts and runs with the wires jumpered, then you've found your issue.

Thanks for the tip knightrous, but no luck. Lack of fuel is not a problem. Carpet snake is still happily living in the shed and not the the air cleaner

Fuse for the EFI (15a) might be blown. Maybe just kicking over from the cold start injector?

Have you tried disconnecting the Coolant temp sensor, & just bypassing it? I've had a similar starting issue, it wouldn't fire up, disconnected the sensor, & although a little rough when first started (approx. 30 secs) runs fine after that.

@Rallyadub the fuse is fine, but it does appear to be cold start only, and no injection afterwards Do you know where the EFI relay is located, none of my fuseboxes have the correct covers with markings any more

Look in the Big Green Book (BGB) manual p. FI 110 The relay is the round knobby looking one in the box near the battery Its the one farthest from the strut tower. You should hear it click when you turn on the ignition. The book has a way to test it if you have a multimeter. The other round one is the injector relay which you can test. The solenoid resistor also comes into play. Look for damaged wires, plugs with rusty terminals and loose connectors and give looms a bit of a shake which might highlight a dodgy connection Good Luck!

You don't have any kind of immobilizers fitted do you?

Hey mate did you get your car running? If not try the computer When starting the fuel pump gets its own earth for about 2 seconds while starting but then when it starts the computer controls the earth so if it's cactus it won't be giving it that earth and like you say it will start but not run
