Starting Issues

9 posts in this topic

Hello guys,I just bought this 1998 993 C4 with 46000 mls,in very good conditions here in south Florida,however there's this starting problem that is getting more and more frustrating...Whenever i start the car (cold or hot) I can actually hear the fuel pump but it doesn't crank...nothing,after a while,messing with the remote control (pushing on and off) and a lot of cursing involved...then it usually starts,I bought a lovely (!) 115$ DME relay at the dealer but obviously I didn't solve the problem....it would be nice to have a good help from you before I putting it on fire! Thanks,Joe a0c74b5b35fa5bcc45d5517456913ea7.jpg

Have you run a diagnostic tool on the car to see if there are fault codes?

That is what the fault codes will tell us.

If the car's systems recorded any anomalies they would be either fault codes or pending fault codes.

These are symptoms of your alarm module failing, unfortunately. You can have it repaired at a local flordia shop for about $750 I believe. ECU doctors ! Perhaps there has been moisture in the alarm computer which explains its strange behavior.

Thanks a lot,do you have any idea where's it located ? Any way to deactivate it?

The most sensible course of action, as Loren has suggested, is to try to narrow it down by way of fault codes.

 

Guess work will invariably prove to be an extremely frustrating and expensive approach.

the alarm module can
be disabled with a racing module that replaces it.
it is sold by ecu doctors but i believe its over $1,000 .
the alarm module is located under the driver seat and the seat has to be completely removed. inspect for signs of moisture. the estimate cost to hve the alarm module diagnosed is $75 which is much cheaper than buying a durametric or having a shop run the codes.
