ON going problem with my 740 Turbo not starting

I have a problem with my 740 Turbo 1988 with 230 motor. It was backfiring and finally died. It was suggested that the time belt had jumped a few cogs. So I started to fix and change a few things. I have put new plugs in, new spark plug leads, new timing belt, new harmonic balancer (as old one stuffed). It is getting fuel to the injector rail. I have cleaned the injectors. Any suggestions? What else can I try, does this model have a crankshaft sensor or some such if so where is it? LHS or RHS side of the motor? I checked the compression it is 150psi in all cylinders?



Please any help would be good

Well I have checked a few more things, the tacho is ticking as I turn the motor. I took the injectors out and cleaned them and checked they were pumping fuel. There is spark at the spark plug end of the lead. Just wont fire Any other ideas?



Thanks

Are you sure you got the timing belt set right? How about the plug wires, did you plug them in exactly the same order they were before? If either of these are off the engine will not run.

Oh also try unplugging the air mass meter and see if it starts.

This is about the point to see if the fuel or ignition is at fault. Spraying a few seconds' worth of starting fluid on the air filter, closing the air cleaner box up and trying to start the engine will tell a lot. If the engine goes "vroom" and quits there is still a fuel delivery problem but the ignition is okay. Otherwise, the ignition - particularly wire connection or timing as James Sweet describes - is suspect. It's always possible the engine is flooded, but that isn't usual.
