Ok,I have read forum upon forum.I Just bought this car for cheap in real good condition.Fuel gets to the rail fine but doesn't make it through the injectors.Kid before me drove it about a 1000 miles before it died and sat in his yard.The motor cranks with no issues.Everything works otherwise.I have no spark at the coil,took the coil control plug off and tested i have the ignition power but no signal when i turn the car over. I've come to the conclusion its the cam angle sensor but I've spent countless amounts of money on the ignition system.It had a new distributor and coil when i got it.all the grounds ARE connected and the connectors are all in the right spot.I have tried 3 different ECU's 2 being 91 Dohc's and 1 a Sohc.I know its not timing cause the distributor could be 180 degree's off and still should get a spark just not at the right time.Would be a wonderful Christmas to get this beauty running. Plz help

Does check engine light come on when you turn ignition switch on? If not then the computer is not turning on. Check relays and fuse links. Ignition relay is under dash. ECCS relay is under hood. Use a test light to check for power to coil, dist, and ecu. Do you hear fuel pump run when turn switch on?

Well, the check engine light does come on. Fuel pump and sending unit is out of my other 240 and does work I hear the pump. The coil has power buy isn't getting a signal from either the computer or distributor Wich both are good.I'm stumped. I have not checked the relay under the dash yet though .
