My timing chain skipped on my 1989 Mustang LX Notchback a few months back, my friend convinced me to re-build the entire engine. A few months go by, the engine's assembled with only the block, heads, & crank re-used. Situation: I put the new engine in, hooked up the sensors, set the timing perfectly, I have spark, I have fuel, I have fuel shooting into the chambers, there's oil on the plugs, I test every possible thing electrical; purchased a new TFI module, the engine had all new parts which were put on correctly, took valve cover off & everything was functioning, tested EEC because I thought injectors weren't firing, they were...I'm out of ideas; the timing is right on! I tried 180ing it for the hell of it, nope. Anyone have any idea?
