Danny's 4door Calypso 24v car

Nobody?

Fixed the fuel pump issue, so we have fuel.
Have spark, at least outside of the motor.
Injectors are firing.
Compression is low, but even. with 6 cranks it has 90 psi, throw some oil in and it goes up to 150.

I think we have everything we should.

Did you stomp test?

Yeah, code 1444: no faults :|

Thats crazy then. Rotating engine tells the DME to power the fuel pump. Air, Fuel, Fire= explosion if timed correctly.

Im with sam. Bad CPS

I have to disagree guys. I mean, if it was the CPS I wouldn't be getting spark. The issue is that there is no 12v at the fuse box.

If its not starting when jumped then its either timing related or the DME is not registering a rotating engine (which would explain your issue with not getting power for the fuel pump). IE bad Crank Sensor or dme

Swapped the DME with a different one and I get the same result. I have spark so that rules out the CPS doesn't it?

Electrical = over my head.

I would be leaning towards trying a new fuel pump... but I often jump a couple steps too far ahead with these things.

Either Relay or ECU related. I was having a similar issue and it actually ended up being the Fuel pump itself. Even after trying 3 different "known working" fuel pumps.

Try swapping the relay and then I'd move back towards the fuel pump. Sucks, homie! Hope you get it sorted.

But even that doesn't solve why the fuse box doesn't have 12v at the slot for the fuel pump and why when we jump the relay it won't start.

yes, had this this same situation and it was a major vacuum leak. Pulled the intake out and zip tied it from 2 sides.

Tried ziptying the thinger, worked fine. I don't think it's vacuum.

If you have fuel pressure and spark (assuming it is at right time) Your injectors must not be opening. Pull your intake boot loose and spray starting fluid past the throttle body. It will start if you are missing fuel. Are your injectors plugged in securely?

They are indeed in securely. I'll give the starter fluid a try.

The situation you are describing COULD be a big vacuum leak. When this happened to me randomly the ICV hose had fallen out. It would have to be a big leak.

Sounds fuel related, it's probably the only thing that didn't come from the gray car, right?

Right, and it's weird that it worked fine for about 30 minutes and they took a shit.

So again, recap:
NO 12v power at the fuse block for the fuel pump.
Have spark
Have 50psi when relay jumped
Will not start when relay jumped

[samiam3356]

Checked that, seems a bit loose but nothing terrible, should I ziptie it so it's real tight?

yes, had this this same situation and it was a major vacuum leak. Pulled the intake out and zip tied it from 2 sides.

Don't have 12v at the fuse box for the fuel pump.
