I tried replacing the CPS to see if that's an issue because I don't get a fuel pump prime when I put the key to start the car.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I redid the timing after a rebuild and i messed up with the rotate 360* between timing each banks. so after i figured that out i rotated the 4-6 bank. Car wont fire up but it is cranking faster than it did with the wrong previous timing. Can the timing be backwards where i should have rotated the 1-3 bank instead. I did the 4-6 bank due to ease of rotating that side instead of the 1-3 bank. if there isn't a wrong way as long as the banks are opposite of each other i'll start looking for another reason it isn't starting.

POST 2Original post

Did it fire up before you fixed 4-6? I made the same mistake. But it did run before I fixed it. Very rough but running. I rotated 4-6 like you because it's easier to get at. Worked perfectly after that. Mine was a 3.4. Shouldn't be any different tho.

POST 3 / ORIGINAL POSTEROriginal post

It didn't fire up before. So that's why I was wondering if I needed to swap both sides or start looking for another cause for it to not fire up.

POST 4Original post

As long as the timing events are 180* from each other, and both have the same correlation to crank position, you can’t go wrong. Post a video of it trying to start. Did you install the cams in the proper location? They are marked per bank. Sounds like you might want to buy my cam timing episode of the Focus on M9X Engine Assembly

POST 5 / ORIGINAL POSTEROriginal post

Im guessing cams are in proper location. You Tube

POST 6Original post

Compression sounds a little weak on one bank. Does the tach needle move up to 300 RPM while trying to start?

POST 7 / ORIGINAL POSTEROriginal post

I dont think i see the tach needle move much. I tried replacing the CPS to see if that's an issue because I don't get a fuel pump prime when I put the key to start the car.

POST 8 / ORIGINAL POSTEROriginal post

When I put on the durametric is get some signal from the tach... like 66 then goes error when cranking. I can run the fuel pump with durametric as well. There were no codes in there except 9110 DME control unit in the gauge cluster section. Anyone have ideas?

POST 9Original post

I have never mistimed an engine, but I have had engines that failed to start. When the head scratching has stopped, I always go back to basics and stopped throwing guesses at it. Is there compression in all cylinders? Is there gas? Is there spark? There is always air. When those are all there, then you move to is cam timing correct. Bring engine to Number 1 TDC, check bank 1 cams Bring engine to Number 4 TDC, check ban 2 cams If those are all correct, check sensor signals and connections.

POST 10Original post

Post a video of the tach behavior while starting.

POST 11 / ORIGINAL POSTEROriginal post

I can post the video but the tach doesn't move. I did install a different CPS and the car didn't change so i put the old one back in.

POST 12Original post

If the tach isn't moving you have no signal. You likely confused the CPS plug with another connector nearby it, and have the two connected improperly.

POST 13 / ORIGINAL POSTEROriginal post

That was my thought... but what plug would fit with the cps plug?
