Buschur Stage 4 has been installed, 264/272 cams, pump and injectors. It was stage 2 before upgrade and running fine. Engine has fuel and spark to plugs. Has power to the injectors but they are not grounding. Thought the computer was the problem but same thing after a new computer instaled. Mitsu tech guy used the scan tool to program new computer and key. Crank and cam sensors appear ok. Any ideas?

 

Did you have the engine out to perform the modificaitons?

 

Is there a chance the cam angle sensor is 180 off? I haven't really looked at mine, but on DSM's you can install the CAS 180 degrees out of time and the car will never run. Also make sure the timing marks are still lined up and that you didn't bend any valves.

 

Ack. Just call Buschur racing, this isn't hard.

 

Well.. no word but I'm guessing that the engine isn't grounded or the ECU isn't.

 

I'd go with the cam angle sensor being 180 degrees out of phase, like 992gnt suggests. If I recall correctly the cam is indexed in such a way that the trigger wheel can go on either way.

 

I will check out the cam sensor position to see if it is 180 degrees out. The engine was not out.
