Okay are the injectors getting power and pulsing? Trying to think through my 92 chevy truck with tbi.
I have to wait until tomorrow to test it. I don't have another hand to turn the key right now while I check the injectors. I didn't hear any sound coming from or see any fuel spraying from the injectors when I had my wife turning the key earlier today.
According to the Painless instructions it says to use pink wire #720 (coil +) to power the ECM and the HEI. I have it hooked up according to those instructions. I sent an email to Howell and Painless to seek further info also. I'll confirm the ground for the TBI harness too.
Edit: I just read on some old post from another forum about connecting the ECM fuse block directly to the battery with some sort of toggle switch in between. I can try this tomorrow also. (Kids are asleep and their rooms are over the garage = no Jeep time)
I just ran a single wire from a 12v power distribution block off the battery directly to the ECM Fuse block and also swapped batteries with the one in my other CJ. Same result, still not starting. Starter is lugging then stopping. Gonna see if I have a spare on my shelf.
I removed the #1 spark plug and used my compression gauge to help with finding TDC compression stroke while I was hand cranking the engine. This is where the rotor wound up on the compression stroke, looks like 180* out. I removed the HEI and all the plug wires and reinstalled. Hoping this is it.
That did the trick, it started up but I only have the passenger side injector spraying fuel. Also, the canister on the HEI is dangerously close to my PS belts. My fans never kicked on during the break in so I had some boil over, trying to fix that now so I can restart, time it properly and figure out the non spraying injector issue. The Throttle body whistles like crazy, is that normal for TBI, its really loud under the hood. Exhaust sounds great!
Fixed a bad relay and broken wire for my e-fans (junkyard parts) and they both work now. Also, both injectors are now spraying but it's flooding during cranking now. Fuel is pouring out below the throttle linkage.
I restabbed the HEI over one tooth and it gave me plenty of clearance with the canister. Rotor is in the same spot as it was when I removed it (when it ran). What should the timing be set at with the HEI and the TBI?
I fixed the injector issue, the ground wire was loose. I pulled all of the plugs and hand cranked the engine to push excess fuel out and the #7 cyl had quite a bit in there which leaked out onto the floor. I left the plugs out for a while to evaporate the rest of the excess fuel. Now I'm concerned about having fuel in my oil pan. The dipstick smells like fuel.
The HEI is reinstalled and rotor pointing at #1. #1 cyl is on TDC on compression stroke. I need to top off my coolant and I'm thinking oil change.
Definitely do an oil change, not worth risking damage.
Will do but its gonna have to wait a few days now. I plan on changing the oil/filter and then priming it a few times each day until I can spend some more time on it again. Would it hurt to put a squirt of oil in each of the cylinders incase those rings are washed out from the gas?
Just drained the oil. There was alot more fuel in there than I expected. I'll spend the next couple of days priming it a couple times to push the new oil through the system and get everything as lubricated as possible. Should I squirt some oil in each cylinder?
You could. It would help with initial compression build up but could also potentially foul your spark plugs. You would probably fine either way.
I couldn't wait, I primed it about 5 times for several minutes each today and put a tiny bit of oil in each cylinder and let it sit for a few minutes. Turned the key and it fired right up!!!!! Set the timing from 0* TDC to 12* while it was running. The PS pump started squealing due to low fluid so I shut it down (probably shouldn't have) and topped off the PS system (it was very low). Went to start it again and now it won't turn over. The starter kicks in but lugs once or twice and quits. I got called out for work so the Jeep has to wait.
