Hello everyone I managed to get the wireing figured out on my 3.4 swap in my 1991 toyota pickup m/t. The donor was a 1996 Toyota 4runner auto .

The car turns over Sparks and sprays fuel but it won't start. I checked the spark plug layout and it seems right. Anyone have any help for diagnosing? It almost started today but still nothing. I ran my odb scan and I only have 2 tranny codes. I also used an extra computer to make sure.

 

There may be spark and fuel, but do you know if you have strong spark and the right amount of fuel?

How is the fuel pressure?

You also need to have the air (intake and exhaust), spark, and fuel all happen right when their supposed to.

Are you sure the spark plug wires are all in the correct spots?

Is the mechanical timing as it should be (i.e. the crankshaft and cam shafts are timed correctly)?
