Car was running -- pulled heads -- reinstalled them -- fire up engine -- after a little while 1 or 2 rockers got noisy, so I pulled the upper intake and valve covers, relashed valves and put everything back together. Historically, I've gone through this a few times without issue... until now.
During this downtime window, I also replaced my headlights (From HID --> stock) and I also installed a new dual-fan controller.
Engine turns over, but there is absolutely no sign that cylinders are firing.
I followed the ever reliable JRichker checklist and still no progress. I do however have a couple things I wanted to share with you in the hope it may jog my memory clear.
- I am getting spark from coil wire, but it did require that I hold the screwdriver closer to 1/8" rather than the recommended 3/8". Otherwise, I would not get spark. I've replaced my original coil with a quality aftermarket coil and this behavior is the same.
The spark at 1/8" was blue/purple.
*** I am wondering if there is anything I could have done (Headlights, fan, upper-intake) which results in a weak coil spark ???
I can smell unburned fuel ..
- fuel pressure gets to 39 when I turn over engine. when I stop turning it over, it quickly returns to 20lbs. Fuel filter less than 1000 miles usage and tank was thoroughly cleaned when Walbro 255lbs was installed.
- TPS=0.85v
- I reseated my MSD TFI distributor (#1 TDC. Pulled the SPOUT, no change)
- Red injector lead produces 12+ volts with key on.
- I disconnected/connected fuel lines. No apparent blockage
- I had a spare ECU and it made no difference.
- MAF plug firmly in place
- TPS connector firmly in place
- Salt & Pepper connectors are snug
- Battery in excess of 12v
- Soaked air filter with starter fluid, key on, held throttle body open, while turning over engine -- Nothing.
No idea or suggestion is stupid or simple. So, if you want to pitch out any ideas, I'm game. Hell, sometimes bad ideas can pull me out of the woods and allow me to look at problem from a different angle.
Any help would be appreciated.
