Ok.

First issue was with the fuel injectors spraying eveywhere. Replaced all of the o rings and got that to work.

next issue. Car cranks and there is spark but thats it.

I trouble shooted the distributor. I have 12v and ground from the 2 white wires so those are correct. Opened up the distributor and checked the wiring in there. Took out each plug, connected a spark plug to it and ground the plug and got spark.

The ecu is not showing me any codes, there are no flashing lights.

What could be the problem?

There is a leftover plug thats ontop of the 3 plugs. If standing infront of the manifold the plug is to the dside, behind the manifold. There are two wires that come out from the manifold and then get connected to a white harness. The wires are.. Blue and then black with either a white or yellow stripe. I have no idea where this plug connects to. I have a 1991 std civic.

All help and trouble shooting with me much appreciated! Thank you

 

post some pics of the plug

 

the blue and black wire with the yellow strip connect to a black and orange wire on the harness it goes to the tandem valve

 

Ive read in multiple write ups that the tandem valve isnt connected. Thats one of the 3 plugs that are not reused. Please clarify.

Thanks

 

it is connected
i also did a dpfi to mpfi conversion on my std civic
i connected the wire and its working fine
am using the pm6 ecu with 91 si intake manfold i got no check engine light
and it started right up on first try

 

the Orange Tandem Valve and Blue FICV wires run to the same place on the DPFI and MPFI ECUs - black/yellow is power

 

Thank you. I will check that out in the morning but i dont believe that this would cause the car not to start.

Anything else

 

orange goes to blue and black to black
check your grounds and b10 b11 c1 and c2 pins make sure there connected
also your main relay

 

Are your plug wires in the correct order?

 

Ok.. this is how the plugs are wired.

From the timing belt to the distributor. 1 2 3 4. They go from right to left in that order.

At the distributor. If you are staring at the distributor. Bottom left is 1 and then next to it is 2. Above 1 is 3 and 4 is given.

Thanks

 

When these main relay goes bad, you will not get fuel or spark. I am getting both.

 

Yes, no fuel or spark with a bad main relay. Your firing order is correct. What about the mechanical timing of the motor?

 

wouldnt the car start even if the timing was off? I read that the distributor could have been installed incorrectly but I am getting spark. I search but couldnt find any solid info on how to properly install the distributor.

Thanks

 

If the timing is off by enough, the car won't start. Do you have all your grounds hooked up?

 

I really don't see how anybody could manage to install the distributor wrong as the notch in the camshaft is offset as well as the key on the distributor. It will only go in one way, unless you worked really hard at putting it in wrong... like with a bfh lol!

As for that mechanical timing, I'm referring to the crank/cam alignment. It's easy to check by removing the upper timing belt cover exposing the cam gear. Rotate the crank to TDC (the little mark that's all alone on the harmonic balancer, not the 3 marks that are together) with the up arrow on the cam facing up and the 2 lines on the cam gear should be straight in line with the head surface.

And just to be sure about the ignition timing, while you're at TDC, pull your cap off and make sure the rotor button is pointing at the #1 plug wire.

 

Thanks. I will check with the timing. Will let you all know what I find out.
