At the end

[F34R]

I just finished swapping my shitty m20 for another eta m20 that was pulled from a complete perfect working e30. Now here is the problem:

I cannot get more than .04 on the volt meter on the fuel pump, when I turn the key on. There is also no more that .04 on the #11 fuse(fuel pump)

I am also not getting any spark when I have my friend turn the engine over and I stick a screw driver in the plug end. I have two ECUs too, and same thing with both.

My question is does the pump and spark run off of the same wire? and why is it that EVERY fuse but the pump is getting juice. I have gone over my harness for 3 hours and had everything hooked up.

I am lost and pissed at the same time. Anyone run into this before? or know why I am not getting juice to the pump? I know there is a relay on the engine bay, middle one of the three. I did not swap that out yet but I thought it to be fine since the car was in perfect shape.

Not kidding, one key and she purred. Reason for the swap was the good engine's body was shit rusted.

Thanks for any info

P.S. can someone take a close shot of the power block on the firewall? And the two prong wires that connect above them.

In this case no spark and no power to the fuel pump when cranking the engine is probably the lack of timing data to the DME. Check the connections to the crank position sensors. They may be disconnected or swapped.

will do, thanks

They were connected but no go. Then I swapped them out from the other tranny to the engine that I swapped in. Still no spark and power to pump. Back to the drawing board.

Have you tried swapping the timing data connectors? Is the main relay closing when you turn on the ignition?

Where are the TDC located? and I will switch out the relay to see if that is what it might be. I just did not think of it, I swapped the m20 from a perfect running e30. It was just really rusty.

The reference and speed sensors come from the bellhousing and should be somewhere near the brake booster. Both are 3-pin connectors that are interchangeable. In fact, they're the same sensor. But, if they're plugged in backwards, the engine won't start.

Yeah, tried those. Held in by hex bolts plug type entry into bellhousing. Connects on the block. Unplugged and swapped them around, still a no go.

What about the OBC? I changed it out for a euro clock, sense I changed the engine out would that reset anything? I know without a code it will disable the car. Could that be an issue?


N/M on that one, since I removed it. That also removed the code.
