1996 Plymouth Neon WON'T START

Hi KRAHEL, Welcome to 2carpros and TY for the donation

Inspect and test the ASD relay and the coil pack driver circuits back to the PCM.

Disconnect the wiring connector from the computer and the coil pack- check the wiring for an open or shorted wire if okay replace the computer

I DID PUT A NEW COMPUTER AND WIRING HARNESS ON.STILL THE SAME PROBLEM.I ALSO FORGOT TO TELL YOU THE COMPREESSION WAS IN SPECS.

Your fuel pressure should be 48psi yours is on the shy side-also check the available voltage on the coils

Hi guys. Check for a sheared off dowel pin between the camshaft and its sprocket if this is a single cam engine.

I AM GETTING VOLTAGE TO THE COILS,AND THE CAMSHAFT IS TURNING WHEN YOU CRANK THE ENGINE.THIS HAPPENED AFTER AFTER I PUT A NEW TIMING BELT ON IT.IT RAN FOR A LITTLE BIT THEN THIS HAPPENED.

THE ONLY THING I DON'T KNOW ABOUT IS THE PRIMARY IGNITION IF THIS COULD BE A PROBLEM.ALSO HOW TO CHECK IT.THANK'S

Turning isn't the issue. It is real common for the dowel pin to shear and over time, the sprocket turns slightly on the camshaft. Since the camshaft position sensor is on the other end of the cam and not by the sprocket, the Engine Computer detects that as though the belt has jumped a tooth. At one tooth mismatch, the computer turns on the Check Engine light and sets a fault code for "cam and crank out of sync". At two teeth off, the computer shuts the engine down to protect it. At three teeth off, open valves will hit the pistons. This only applies to the single cam engine. I've never heard of it happening to the DOHC engine.
