Replying to: smokeybarnable (Feb 04, 2006 11:27 am) i took the ignition coil out and did the ohm checks listed in repair manual. The coil passed all tests. So I hooked it back up and took one of my front wheels off to access the spark plugs. I took out one plug and hooked it back up to the wire and then cranked the engine....the spark plug didn't spark! I double checked that the wire from the coil to the distributor is sparking...it is. Thats where im at now. Haven't checked fuel pressure yet Replies to this message: cob (Feb 08, 2006 9:11 am) just_lucky (Feb 22, 2007 10:57 pm) just_lucky (Feb 22, 2007 10:56 pm)

Replying to: smokeybarnable (Feb 07, 2006 3:03 pm) If you are getting spark from coil to distibutor but not to plugs, The suspect would be the cap and rotor or the plug wires. But, since there is no firing going on the wires are probably fine its got to be under the distibutor cap. Replies to this message: just_lucky (Feb 22, 2007 10:57 pm)
#22 of 37 Future Issues with my 02 safari by tinam3 Mar 03, 2006 (2:47 pm)
I recently had several instances where the check engine light came on and went off. when investigating it was a misfire on #5 caused by wear on my plugs and wires. I have it fixed but am now wondering what else might need attention in the future. It only has 50K miles on it and I have kept up on the maintenance.

#24 of 37 i have the codes...what could this be? by kirby75 Oct 08, 2006 (6:46 am)
i have a 93 astrovan 4.3. the abs light and the service engine soon light go on and off intermittently. i have the code reader and it tells me that the ecm code is    "#43 electronic spark timing (EST) circuit - low voltage detected / electronic spark control (ESC)- circuit problems".   and the abs fault is "#8 shorted dump valve circuit or faulty ecu".   both these lights started coming on within a day of each other...i kinda sounds like maybe something is not putting out enough voltage or something. any ideas what it could be??... thanks
#25 of 37 check eng. light CODE 1141 evap. cann. system by bsmoodha Oct 19, 2006 (4:55 am)
I have a 1141 code which relates to the fuel cannister evap. system on my 98 2WD van. I have replace the gas tank cap with a new one from the dealer. I have replace the purge solenoid on the intake manifold also. I still have the fault. Has anyone had this same fault and if so what was the fix.   P.S. I am fairly unhappy with all the little problems this vans has thrown at me for the last 8 years. The latest big one was the now infamous coolant leak from the poorly designed intake manifold gasket.
#26 of 37 ABS & Brake lights stay on by jethro95 Dec 10, 2006 (5:07 pm)
I have a 90 Safari. I recently replaced both rear brake cylinders & shoes. And after bleeding the brakes, the dasboard brake light went out, as expected. Just a day later, the brake line itself started leaking, both ABS & Brake dash lights came on. After replacing brake line & hose to rear axle, bleeding brakes again (even bled front brakes), The ABS & Brake light still stay on. I have a good pedal,& brakes seem to working fine. I have even disconnected battery cable overnight.   I have asked a few people, even a mechanic freind. The usual answer, "GMs do that a lot, I wouldn't worry about it".   I would like to sell it, but I don't think this will look good. Any ideas or suggestions?  Thanks!
#27 of 37 Check engine light stays on by jasonbro Jan 26, 2007 (12:45 pm)
I bought a used 1997 GMS Safari and there are some small issues I would like to get fixed. The price was too much to resist.   The check engine light stays on. I am new to this and I can use some help. The van drives fine, starts good and the motor sounds really good.   I understand that there are code readers out there that can reset the computer; is this correct? What type of reader works the best?   I also noticed that the airbag light stays on, can anyone tell me what to look for?   Finally the horn doesn't work.   Any and all help is greatly appreciated.
