Replying to: leoman09 (Jul 05, 2009 7:09 pm) If you have not yet figured this one out, please check the fuel pressure and report back if you have any pressure in the system when this condition occurs.   I have the same problem - it occasionally fails to start, but no problems at all when it does start! I can run it for hundreds and hundreds of miles without incident, but if I shut it off all bets are off as to whether it will restart. I have found that when it does not start, there is no fuel pressure. But, it is difficult to determine what is causing this. I would think that if the pump itself was the issue, it would fail occasionally during use, not just between uses. I am leaning toward an electrical problem, but the circuitry is complicated because it is not just a relay that governs the operation of the pump. I have thus far determined that the controlling relays (fuel pump and ASD relays) are fine, so it is either further down the line or further up it. But, the fuel injectors are receiving signals as though there should be fuel pressure, so I have to conclude that it is most likely an issue closer to the fuel pump.   I am checking this tonight; if there is no power to the wires at the pump connector, I am going to bypass the normal circuitry and just wire a relay directly to the ignition wires so that the pump operates when the ignition is 'on.'

Replying to: xwesx (Aug 10, 2009 11:48 am) Fixed the problem - it was, indeed, the fuel pump. After that, I could not use my OBD-II reader, as it would not link to the vehicle. I figured that one out, too - a bad fuse (figures!). Anyway, the van runs like a top again, save for the console lights blinking (but does not affect the operation of the buttons). I know I read somewhere about how to get those things to stop doing that, but I cannot remember where. I suspect an owner's manual would state the procedure, but I do not have one.   213,000 miles and counting.... Replies to this message: xwesx (Aug 27, 2009 1:53 pm) xwesx (Aug 27, 2009 2:30 pm)

Replying to: xwesx (Aug 17, 2009 9:51 am) Okay, I found a site that has the answer to this question of blinking lights on the console!   It is an HVAC calibration process that is required after a battery disconnect:   http://autorepair.about.com/library/a/1i/bl667i.htm Replies to this message: xwesx (Aug 27, 2009 2:30 pm)

Replying to: xwesx (Aug 27, 2009 1:53 pm) And, when there is a problem that occurs during the calibration process, here are what the trouble codes mean:   HEATER AND AIR CONDITIONING DIAGNOSTIC TROUBLE CODES (DTC's) DIAGNOSTIC TROUBLE CODE (DTC) DEFINITION/DRB III® DISPLAY 0 PASSED ALL TESTS 1 MODE ACTUATOR DID NOT REACH "DEFROST" POSITION 2 MODE ACTUATOR DID NOT REACH "PANEL" POSITION 3 BLEND/PASSENGER ACTUATOR DID NOT REACH "COLD" STOP 4 BLEND/PASSENGER ACTUATOR DID NOT REACH "HOT" STOP 5 FIN SENSOR "OPEN" 6 FIN SENSOR "SHORTED" 7 ZONE/DRIVER ACTUATOR DID NOT REACH "COLD" STOP 8 ZONE/DRIVER ACTUATOR DID NOT REACH "HOT" STOP 9 CONTROL MODULE INTERNAL FAILURE   Note that if a system fails, the intermittent wiper button's light will flash the appropriate number of times, followed by a single flash of the rear wiper button, followed by either the next trouble code or the same code over. Once all codes are read out via flashing, the first code is repeated.   In my case, codes 5 and 6 appeared, indicating fin sensor "open" (5) and "shorted" (6).

Replying to: xwesx (Aug 10, 2009 11:48 am) Can anyone tell me where the crank shaft position sensor is? And or the automatic shut off down rely is? I see a ASO rely, automatic shut off? anyway same issue it won't even turn over....   PD Replies to this message: xwesx (Sep 29, 2009 5:15 pm) pauld2100 (Sep 30, 2009 12:47 pm) pauld2100 (Sep 30, 2009 2:02 pm) xwesx (Sep 30, 2009 3:08 pm)

Replying to: pauld2100 (Sep 29, 2009 5:05 pm) The crankshaft position sensor is located on the transmission housing, just aft of the engine. If you pull off the air box (that is bolted to the cross member in front of the engine) as well as the tubes that connect to the throttle body and the air cleaner housing, you can see the sensor one the back side of the transmission housing just behind the engine. It is a little easier to find if you locate the wiring harness that plugs it in and follow it up to the sensor.   As for the ASD relay, it is the first of the larger black relays in the strip, on the right side top if you are looking at the unit from in front of the vehicle. there is a small 10-amp fuse located directly "above" it, and the fuel pump relay is directly below.   At least, this is the lay out on the 1998 Caravan - I am not sure what you have or how it is laid out.

Replying to: xwesx (Sep 29, 2009 5:15 pm) Ok thanks, I have a 2003, and the air cleaner is on the passanger side and the trannys on the driver side, so I also had a code PO134 O2 sensor is what it's calling bad... Is that crank sensor on the tranny itself or on the engine? Replies to this message: pauld2100 (Sep 30, 2009 2:02 pm) xwesx (Sep 30, 2009 3:08 pm)

Replying to: pauld2100 (Sep 30, 2009 12:47 pm) It is on the bell housing between the engine and transmission (although the housing is part of the transmission). The sensor reads off the pressure plate, which is mounted directly behind the engine and is inside the bell housing.

Van is having a hard time starting. Problem just started the last 3 times I went to start van. Gas, Speed and Temp gauges started acting wacky going from left to right and then back again(never done before) and it seemed hesitant to turn over. Now car doesnt really want to start at all. Any advise please???? Replies to this message: cbwilsha (Nov 08, 2009 12:44 pm) pauld2100 (Nov 08, 2009 2:13 pm) ilsotb98 (Nov 08, 2009 5:57 pm)
