I know this topic has been covered before, many times, but I just wanted to document the problem and relate what I did/will do to fix it.
This has been going on for several months. I have had to tow it home twice. The car will just kill/stall/stop running, both while driving or at idle. Then it won't start. It will turn over, i.e. the starter is turning, but it won't start. This has happened at 40 mph, 75mph, at a stop sign, while making a "coasting" left turn through a light. Sometimes it will start right back up, somtimes I have to wait an hour or so, sometimes a day or so. It also seems that once it starts doing this, it won't work till I fix/change/dwiddle with it. It is also hard to diagnose since it is so intermittent.
I am very familiar with the posts on this website, along with Deja/Google, along with Yahoo Groups, ... but I haven't seen any concrete solution to this problem; i.e. fuel pump, ignition module, crank sensor, ground, VATS, ... I hope that by chronicling my attempts I can help somone else, or get some additional ideas from some of you, and to hopefully get some direction or help from you guys.
As I said earlier the car just dies and won't start again for some time. No warning lights, no Security Warning, and no ECM/PCM codes. The only common I can find is that this happens immediately following a "coasting" decellaration; i.e. stopping for red-light or letting off the accelerator on the highway.
I plan to try all of the possible solutions I have come across. And post the results here.
Things I Have Already Done:
1) Changed the Positive Battery cable connector since it seemed loose and corroded.
2) Replaced the Crank Position Sensor TWICE!
3) Sealed the Crank Position Sensor Connector with RTV
4) Checked for ECM codes; none.
Now the battery cable did help a little, i.e. the car ran ok for about a week. When I changed the Crank Position Sensor the first time I noticed oil seeped into the connector. When the car died a week later, I pulled the sensor again, more oil, cleaned it and the sealed the connector with RTV; i.e. around the pretty blue grommet and on the outside. Lasted about a month. This last time I got hold of a Scantool but no codes were present;i.e. current or history.
Maybe you guys might know about this. But I have noticed I have a persistent oil leak on the bottom of the engine and in the past the Crank Position Sensor has been covered with oil/grime. Now that the connector is clean and protected, what if the sensor itself is coated with a thin film of oil? SInce it is a Hall-Effect sensor, could oil foul up the reading and cause the car to shut down????????
Thing to Be Done:
1) Replace the Negative Battery cable terminal.
2) Check grounding points; i.e .corrosion, good contact
3) Test ignition Module at Autozone
4) Test/Verify sensor connections/wires. Especially Ignition Module ground strap
6) Check out the VATS system for correct operation
7) Fuel Regulator
9) Fuel Filter
10) Fuel Pump/Gas Tank Pickup
11) Check/Test Fuel Pressure (dependent on repeating problem)
12) Test/Check Ignition spark present (dependent on repeating problem)
I would appreciate any advice on the 12 items on my to do list. I am going to try to diagnose/test these components before replacing them.
I will update this thread as soon as I have any information
Thanks for your help in advance and congrats on a great web site.
