#29 of 37 92 Astro... ABS Warning Light Reset by old_car_nut Feb 05, 2007 (9:59 am)
Hello out there...   My ABS light and the red brake lights came on the other day at the very end of a long stop on a slippery road. The brake pedal went just about all the way down during this sequence but nothing seemed to be wrong. Just as the car stopped, the lights came on.   I think it is a nuisance light since the brakes, front and rear, work just fine. My question is... How do I reset the ABS module to see if there really is something wrong?   Any help is appreciated. Replies to this message: cob (Feb 06, 2007 9:21 am) old_car_nut (Feb 13, 2007 7:21 am)

Replying to: old_car_nut (Feb 05, 2007 9:59 am) Reset the ABS light by removing the neg battery cable for 5 minutes to reset the codes. I would also check you brake fli=uid level in the resevoir to make sure that is not the source of the red brake light coming on. Replies to this message: old_car_nut (Feb 13, 2007 7:21 am)

Replying to: cob (Feb 06, 2007 9:21 am) I put a jumper on the communications link to get the ABS light to flash a code. I got a 63. Does anyone know what that means???   Thanks

Replying to: smokeybarnable (Feb 07, 2006 3:03 pm) i gotta agree with cob. i very recently had hard starting and rough running til i went in the distributor cap and bent all the tips in to be closer to the rotor as it passed (you'd be amazed at the gap inside the cap from the tips of the cap to the rotor tip)and sure nuf it starts like the vehicle was just rolled off the producion line ... i carefully measured the safe amount to bend inwarded with no touching between rotor and dist.cap and i suspect i may have changed the timing a very little bit due to the spark being able to jump a slight bit sooner but if the vehicle senses stuff like that , well i guess it might compensate( if it has the ability) for the timing advance if any

#35 of 37 fuel injector failure by trevor14 Mar 20, 2008 (8:41 pm)
Having problems with a cylinder loading up with fuel and fouling a plug. Did a full tune up, ran a fuel injector cleaner, scaned the motor, did a fuel preasure test, no codes but a flashing engine light( meaning a missfire and your converter is loading with fuel), replaced the fuel injector system in the intake, checked for leaks in the intake and lines, and still no differance in proformance. I then decided to check the wiring from the fuel wiring harness (top of the intake) to the computer harness and low and behold the wires from the comp side had been laying on the van body under the battery and had wore through causing the one fuel injector to stay open.

Replying to: deweyman (Sep 05, 2006 10:12 am) check the wires from your computer by the battery so they are not touching the van body
