My van will not start. The battery went dead and it was jumped. Did not start. Disconnected the battery and recharged it. Reconnected once charged and tried to start it. No go. No sparks at the distributor. What could it be? Thanks. 3.0 engine.

Test the ASD relay -this one here powers the injectors and the coil-check both for power input then comeback asap

I have check for power at coil in power wire. When the switch is turned on the power comes on for a very short time and then goes off. Could it be the computer? Conrad.

I try not to get to the brain that's my last resort its an expensive component. Does it do the same at the injector-if it does-The computer ASD relay controlled is inoperative

I interchanged the relay but it did not make any difference. Any other idea? Conrad.

No sparks at the distributor.

Inspect and test the crankshaft position sensor on the transaxle bellhousing

The crankshaft position sensor appears to be ok. Still having a very short duration power at the coil positive wire but nothing else. Conrad.

NO-START TEST

NOTE:Perform TESTING SPARK AT COIL before proceeding with NO-START TEST.

Unplug coil connector and coil. Connect a pair of jumper wires between coil and coil connector. Ensure sufficient battery voltage (12.4 volts) is available to crank engine and operate ignition systems. Crank engine for 5 seconds while monitoring voltage at coil positive terminal.

If voltage remains near zero during entire period of cranking, see TESTS W/CODES - 3.0L article in the ENGINE PERFORMANCE section to check PCM and ASD relay. If voltage is near battery voltage and drops to zero after 1-2 seconds of cranking, see TESTS W/CODES - 3.0L article in the ENGINE PERFORMANCE section to check PCM circuit.

If voltage remains near battery voltage during entire 5 seconds, turn ignition switch to OFF position. Disconnect PCM 60-pin connector. Check 60-pin connector for loose terminals (push-outs). If connector is okay, go to next step.
Remove positive lead from coil. Connect a jumper wire between positive battery terminal and coil positive terminal. Using a specially constructed jumper wire, momentarily ground PCM harness connector terminal No. 19. See Fig. 2 and Fig. 3. Spark should be generated when ground connection is disconnected.

If spark is generated, replace PCM. If no spark is generated, use special jumper wire directly on coil negative terminal. If spark is produced, repair wiring harness for an open circuit. If no spark is produced, replace ignition coil.

Have you checked the timeing belt, I have seen these enging sheer a few teeth off of timeings belts, and if that erar of the belt is at the crank pulley the belt wont turn, there should be a cover you can remove to see if the belt turns when the engine is turning over
