no spark after BHG repair

[Chaingun]

So the car is back together, but for some reason i have no spark, I've completely rewired the CPS but i haven't had a chance to test it, the Ignitor or coil packs per the TSRM, aside from those parts is there anything else that could cause it not to spark?

 

[hvyman]

The ecu grounds on the intake manifold.

 

[Chaingun]

hmmm can you discribe the wire i should be looking for? the only grounds i remember removing for the electronics was on the coil packs and the tiny ass ground attatched to the rear lift point, your most likely right and that ground is all i need to fix just not sure which one it is lol

 

[hvyman]

It's 4 wires. 2 white and 2 brown that go on abolt on the intake manifold. They can make there way on the starter easy.

 

[Chaingun]

You are most likely a genius, i remember putting them on the bolt, the ones next to all of the old auto transmission wiring but i'll be damned if i can remember if i tightened said bolt down, hopefully that's all it is cause this last month without my car has been hell, i miss my supra more than a sane man should

 

[Chaingun]

well the grounds were fine, and i was able to start the car, it apparently had lost enough fuel though evaporation to have none in the tank, i put some in and started her right up, now it appears that it's idling too fast about 1k, where it should only be around 650 IIRC but i can't retard the timing anymore with the CPS it's at the end of the flange already, is this normal?

 

[hvyman]

Set the timing to spec. 10* btdc.

Did you mess with the tps or throttle linkage at all?

 

[Chaingun]

at the risk of sounding stupider than i have already proven to be, how do i do that, the TSRM states to set the motore to TDC first, should it really be lined up with the 10* mark before the CPS is installed?

Call me curious but how does an empty fuel tank result in no spark?

 

[Chaingun]

the no spark condition was due to a connector on the coil pack harness that had pushed out, with that resolved i got spark again, but still no start. Then i was proven to be a dumbass when my buddy asks does it have gas in it? to which i replied It did when i parked it. Turns out that crap evaporates go figure

 

[jetjock]

Yeah, go figure. But since the fuel system is sealed where did the fuel evaporate to? Bear with me. Not being the genius hvyman is I often need explanations....

 

[Chaingun]

I removed the charcoal canister lol didn't plug it yet cause i don't have a vented gas cap

 

[hvyman]

Yeah, go figure. But since the fuel system is sealed where did the fuel evaporate to? Bear with me. Not being the genius hvyman is I often need explanations....

Thats the most i seen you type in like 3 months. lol.

 

[Chaingun]

It lives! I was able to start the car and we're working on timing now, gotta go buy a decent light to do it though also need to find an exhaust leak seems like a pretty bad one too
