1995 saturn
I need some help. I bought a used 95 saturn with ablown engine ( original
engine had a blown piston- odometer read(s) 83,000 miles). bought a used engine and swapped the old out and fthe new in. new engine won't start. gets spark ( simple ground test used); gets fuel to injector rail ( pulled line loose ); pistons have compression ( did compression test ). now I admit I am not a " mechanic" but this is the third car that I changed engines on ( previous- 85 cougar, 98 taurus ) got them to work -thought that this would be nice project for my teanage son and me. any thoughts where I might look to find the problem?? what happens is the engine turns but won't start. |

Just to be sure try a "little" Starting Fluid. If it hits on that then you know you have a fuel delivery problem. |

I will try working that ...fuel pump " whirls" but it does seem to be a little low in pressure at the injector rail..... |

Get a fuel pressure gauge and measure it.

Check your fuel pump pressure and compare to specs. If you don't already have a Chilton or Haynes manual for the car, it's time to get one. Try eBay -- that's where I got mine, quite a bit less than half price. And, as one other poster suggested, give it a little shot of ether (starting fluid) and see if it lights that off. If it does, your problem is definitely in the fuel system. If it doesn't, the problem is probably in the ignition system. -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |

> Pull an injector, and make sure it's clean -- fuel won't get through a clogged > injector. The best thing to check flow is to do a pressure drop test. One would need a fuel pressure gage (30 bucks) a tool used to pulse the injectors (80 bucks). Like so Cyl 1: run pump-take reading-fire injector-take reading Cyl 2: run pump-take reading-fire injector-take reading Cyl 3: run pump-take reading-fire injector-take reading Cyl 4: run pump-take reading-fire injector-take reading > Check your fuel pump pressure and compare to specs.

Its either pressure or no command from the ecm to pulse the injectors. |

A better question is what he did with the engine that he's not using
