hello, i have a 95 eclipse gst. Originally i parked the car to wait for my friend. When he arrived a little while later, the car would just crank, engine would rotate but not start. I towed it home and replaced the cam and crank sensors, timing belt, and timing belt tensioner. I retimed the motor, tried to start it, and it still just cranked. No fuel was getting to the engine. I replaced the fuel pump/mpi relay. Still no power to the fuel pump hot wire. I ran battery voltage thru a seperate relay i wired in and finally got the pump to power up when the key is on. Now i tried to start it again, the car backfired out of the intake and jumped timing. I have just taken off the belt and tensioner again. Im gonna replace the tensioner again. I also removed the intake cam gear and found the blade that slides through the cam sensor is bent. Would this give a faulty reading and cause my car to not start? how can i keep the car from jumping timing again? Is there some special way to tension this belt? i know to use the auto tensioner and then snap ring pliers to further tension it? Am i missing something? i need to get this car back on the road. Thank you in advance for your help.

The cam blades for the sensor being bent is probably what cause your timing to jump. The real question is how many teeth did it jump? You most likely will need to pull the head and replace any bent valves. Jay racing sells the full timing tool kit for our cars and its a well worth investment. I've timed hundreds of mitsu's timing belts with my set and have never had to second guess my work, even before I had them I could easily get them done quick and easy. Anyway your welcome to retime the motor and get a new tensioner, but I don't think that's your problem. If you do I would do a compression test first thing and go from there. The other tool your really missing is the long bolt that can be inserted to hold the tensioner arm in place and get it in the proper place to set the tensioner pulley. As far as your fuel problem sounds like your relay could be bad or power or ground wire is fault, best to do the pump rewire and eliminate that problem, of you ever plan to mod the car and run more boost its a must to do.
 
Not likely bro jumping 1 tooth maybe, but 2 is definitely death to some valves, there's no minimal amount with a interference motor most that jump even 1 tooth bend valves! The crank sensor doesn't control the fuel pump turning on if that's what your asking. I believe it only places part on injector firing, and or spark timing. Question before we go any further? When you replaced the timing belt after towing it home, was the timing on before you took the belt off??
 
i already did the fuel pump relay rewire. I would like to retime it and see where im at. Im guessing the off timing caused the backfire. Is there a special way to time it? like what gears to put the belt on first or anything?

yes the timing was on
 
Yes put belt on both cam gears and making sure they are perfectly timed, and no slack between them, then wrap around clockwise so the idler and oil pump are next followed by the crank pulley. This way all the loose is by the tensioner pulley and it can tension like its supposed to. Make sense?
