Engine Died Now Wont Start

[MrStabby]

Ok i was heading north up the hill to the harbour bridge and the engine just stopped. Cranked for a bit, restarted, got to the top of the hill then it died permanently. I assumed it was fuel pump, have swapped it with a sard (which i can hear priming ok) but it still wont start. Checked CONSULT - no errors.

What do i do now? What's the easiest way to check for spark and injector operation. I can't hear the injectors over the engine cranking noise, and i don't have anyone to listen for me.

Sounds like a CAS issue.

How do i check it?

Is that something CONSULT will miss?

[MrStabby]

Ok, i pulled the CAS, spun the shaft and the injectors clicked. So i guess that means its fuel pressure or spark.... I'll check the coil transistor is putting out 9V to the coils next i guess...

Fuel check? - Pull the plugs to check for wet electrodes

Ignition check? - pull a coil and plug out, allow to earth on cam cover. have sum1 else check if the plugs sparking

thats what i was going to say, if you have a dodge plug or injector car will still run, just like a bucket of puss. if your crank angle sensor is playin up car wont fire at all as far as i know. checking it.... hmm replace it?

Electrodes are dry....

Yep i have spark. Didnt look that strong but it was in direct sunlight.

I've pulled the fuel filter, and blew it out the inlet to see what came out. The petrol looks cloudy. Maybe it is/was blocked so i'll put it back together to see if I can start it. I had no luck getting new filter tonight. Repco/Auto-one havent heard of late night shopping.

any updates on this... im having similar issues

[MrStabby]

Ok update: I ran a temporary wire from the the battery to the fuel pump and could start the car, so i know its definitely the fuel pump power circuit. The sound i thought was the fuel pump must have been something else....(HICAS? ATTESSA?)

After tracing the wires it appears i have a problem with the "fuel pump control modulator". I never even knew i had one...still dont know what it does. Anyway, i found one of the plugs was burnt so I opened the unit and found a dry solder joint. Re-soldered it but is still doesnt operate the pump. I guess i'll get another one from a wrecker and swap it out.

The other thing i like to check is the fuel pump relay - does anyone know which one it is?

the fuse for the fuel pump is in with the normal fuses and the relay is in the boot near all the hicas fuses etc i thinkl been a while

fuel pump relay is located next to the driver side taillight behind the boot trim.. we have similar issues.. mine i had to earth the relay with new wire.. traced it to the FPCM on the back side trim and made another earth there.. havent opened the unit up like yourself to check the damage but sounds like a good idea..
