well my ca still won't start i checked my security light and tested 3 diffrent ones in there and they don't come on when i insert the key.
also i bypassed the vats with a resistor and it still does not let the security light come on. now the fuel pump does not buzz either so i don't know what to do.
i had the battery tested and it is good, the starter was tested and i replaced the solenoid. also i used a voltmeter and they got juice. i tested the clutch switch and it has juice. so why doesn't the vats security light come on when i put the key in? should i pull the vats module out and try bypassing it from there? i know it is some where above the radio right. but my car is already torn apart and will take me 1 week to put back together!!! but oh well i have to have this thing running soon because my wife needs to go out of town this week...

 

well i can't seem to get the aldl to go into diagnostic mode as well!!!! maybe the ecu is screwed???... or i did not have the right thing pluged in. the haynes crap book shows it to be the 2 upper right plugs as the a and b... but that connector is labeled. the connector on mine is not also i don't know if i have the right connector mine seems to be at the base of the column in the middle??? is this right and if so i tried running a wire between the top 2 left ones and i got no lights on the dash???

 

 

i have that pic already... but as i said i shorted the 2 ab's but i get no lights i think i have a bigger problem than vats...

 

Check the CRANK fuse and circuit.

Check the ECM/Fuel Pump power fuse and circuit.

Does the SES lamp light at all when the ignition is turned on?

 

the only light is the infl light... also i checjked the fuel pump fuse and it was good... i also forgot... the previous owner hot wired the fan so it would come on as soon as you turn the key on. the fan does not come on now...??? no fan no ecu... what am i to do.!

 

well good news and bad i got the car running but without my fuse in the gauge spot... it won't run at all with the fuse plugged in but cranks ok without it. but it runs reeeeeeeal rough and it kept dying yesterday its wierd ... it also is showing that it is running at 260 degrees 5 mins after starting but... its real cold out side plus i turned the car off and i have a purge valve on my radiator cap so i purged it and no air seeped out... and then i removed the cap and nothing the antifreeze was fine. wasn't hardly even hot. the engine also felt normal to the touch...
it sputtered pretty bad a couple of times last night and the fuel shot out the xtreme lid twice...??? any ideas? i checked all the plug wires and they are good...

 

You may still have a VATS issue, since the "GAGE" fuse powers up most of the ECM sensor and load relays, and probably the starter enable relay. I don't have a '92 schematic, so I can't be certain.

 

see thats the funny thing the securrity light comes on now but my rpms andtemp and oil pressure are dead since the fuse is out... but the car runs like poop!!!! we think it may be bad plug wires my buddy got a good hit to his shoulder while leaning over the distributor!!! they must have got damaged when i moved them out of the way of the headers???...
i also changed the plugs so maybe that has something to do with it. also i put a straight pipe on it instead of the cat. along with a new o2 sensor. whatz weirder is that after about 8 mins of driving it smooths out alot but if i stomp it it hesitated and stumbles pretty bad??? well any ideas?

 

ok i am a complete moron...!!! in the process of trying to fix the vats i papercliped the aldl... and i did not realize it until it was way too late!!! the car is still running very rich!!! i would put my stock prom in and see if that would work but... 2 of the pins broke off during removal!!! oopsss!!!
so i am hoping its the prom and not the ecm itself...???

 

I tried to run my car with the paper clip thing too

was rather amusing, till I figured it out...

 

yeah but now my car doesn't run right at all!!! it is running aweful so i think i screwed up something!!! but i need to know if i need a new ecu or just the prom. i can get an ecu at the junkyard cheap or i can have my friend reburn thwe chip.
