I bought a book on the shadow (my car is a 1993 Daytona ES) and i cant get the timing set right i set it like the book said to it idle's fine but when you rev it it has no power and tachs out at 3,000 rpms... Does the computer have to be reset if the battery is taken off or is bad (dead) for a long time?? When i turned the key on all the lites on the radio came on and wouldnt go off... If and one can help it would be extremely apprieated.

Did you just do a engine swap? Are you using a 93 ECU with the 93 wiring harness? a 90 ECU uses a SBEC 1, while a 93 uses a SBEC II, the main difference is that the 90 sets the fuel injectors off in pairs, while the 93 sets them off indivually.

You did pull the coolant temperature sensor when setting the ignition timing? and put it back on when finished?

Last, for no power you might have a vacuum leak

Also was the engine and heads rebuilt, the 90 had valve seal problems which would leak oil into the cylinder.

I think the seals are good cuz it dont smoke but I didnt adjust the cams yet and I am using the ECU, wiring harness, and intake/injectors from my old engine... I dunno bout the vacuum leak i havent checked that yet either.

Not only that but the 90 engine uses low imped injectors and the 93 uses high imped injectors

read this.... I called the dealership and they said that it sounds like the computer needs to be reprogramed sence it has been sitting with a bad battery for so long... What do you guys think???
