Computer problem.

Open it up and inspect everything. Specially the blue capacitors. Look for leakage on the board

finally

hey man finally got her fixed.it was the computer so replace it and youll be set.i never thought a bad ecu would make the fuel pump run constantly like that,but it DID.it fixed the constant running fuel pump and the injecter pulse.then mine wouldnt fire after i fixed that problem so i replaced the pip inside the distributer and the ignition module was new.tested the coil and it was good.pulled the coil wire and it was bad.should have checked it before the pip but the wires are only six months old but you can never tell about a wire cause it can look good on the outside but we screwed on the inside.anyways,im back on the road and youll be too soon.advance auto has that ecu for $97 bucks plus yours as a core.peace
