My 97 Grand Caravan will not turn over. It has the 3.3 engine. I pulled into a parking lot, shut off engine, went in store. When I got back in the car and turned the key, there was no sound from the starter. My dash lights and head lights are full and bright. The only sound I hear when I turn the key is the ticking of the relays in the Power Distribution Center.
I tried the usual, checked fuses for power and continuity and swapped them around (keeping the same amp rating) after they all tested good, swapped relays around, tried a jump start, cleaned all battery
contact points as well as contacts on the PDC and starter. No change. The starter has full power on the battery connection, but the smaller brown wire on the solenoid does not light up my grounded test light when I turn the key to start position. I pulled starter and had bench tested and it was good so I re-installed ( I did check the motor by turning the crankshaft with my breaker bar while I had battery diconnected for terminal cleaning).
I pulled the steering shroud and looked for broken wires. I pulled the relay, and tested the port for terminal 85 for ground by clipping to the positive batt term and turning the key to start, which lit up the test light. I ground the test light and tested for power in port 30 and 86 with the key in start. Power at 30, but 86 is dead. If I understand this right, i believe 86 should light up at start position and if it it does not the relay wont fire. I did say that I heard clicking in the relay box, but there are several that fire upon start and I could not feel the starter relay click when touched. I tested all my relays for continuity and activity when hot, and all worked properly.
I tested the wires coming out of the ignition switch and the results were as follows : Yellow Wire- no power in any key position, Blue- hot at start and run, Black/white- Power at run, Red- Constant hot all positions or no key, Orange/black- hot at run, Pink/black- Constant hot all position and no key, the Grey/black and Black wires had no power in any position. If I am reading the wire diagrams I've seen correctly, they seem to indicate the yellow wire, which goes to the fuse junction box under the dash, should be hot at the start position. I tried replacing the ignition switch and nothing changed.
I have tried jumping the solenoid terminal on the starter using a start button, when the key was turned to start and I pressed the start button, I heard the solenoid make a loud bang that sounds like the bendix engaging and its thrusting the armature forward but doesn't sound like the start motor is turning. I found this curious as the starter had bench tested good.
I tried to find a blue/yellow wire leading to the range sensor harness but there is no wire that color in the harness. My range sensor has 9 wires entering the harness (White, purble/black, blue/black, purple, purple/white, purple/green, black/white, yellow/brown, and a green/black). I am not sure how to trace out the sensor to test if it is working and not sure if the lack of power in the yellow ignition wire is disrupting something in the fuse panel that might prevent power from getting to the sensor.
Another question involves figuring out which wire is supposed to supply port 86 for the starter relay. My wiring diagram shows the yellow ignition wire transfering power to a red/yellow wire leading to the relay after passing through PTC #10 on the interior fuse panel junction block. But the yellow and the red/yellow wire have no continuity and both have no power.
When this cropped up, I found a thread Richard had responded to that was addressing the the same issue, which is where I found the info to trace out what I have tried. My van is in the exact condition it was when this started. I turn the key, the dash lights up like normal, but the starter does nothing. I would really appreciate some assistance to get my bad girl running again. Can you help? Dale
