Ok, had the new engine runnin last weekend, started setting timing and timin light died so was gonna finish this weekend. Well it wont run at all. THe plugs are getting gas soaked and its flooding out. Ive already swapped my plugs twice today, when i take one set out I clean em and dry em, but then after one start attempt they are soaked again. I have no clue what is the problem, all I know is that this morning it started but was only running on one bank, found one of the wiring harness grounds for the drivers side had come loose, hooked it, now both sides are flooding. This has the edelbrock mpfi upgrade for tbi trucks. The IAC, the TPS, the coolant temp are all new sensors. Also Ive tried to set the timing without a timin light today gone way retarded to way advanced and still no start. Only thing changed since last weekend is the starter. Thanks for any help. Chris.
