Please help a newbie..Targa won't start
 
OK so I am finally getting to work on a project. I have an 85 Targa that was initially bought to donate it's drive train for another project. That didn't pain out.

OK so here is my problem. It's an 85 Targa... The engine cranks over real strong but it will not start. Normally that would be an easy fix. Check to make sure your getting fuel and spark etc...
Here is the problem... I am used to american cars and not quite sure where everything is... I didn't hear the fuel pump which I assume I should hear kick on...

So my question is... what are common problems that would create this.. like fuses relays and such.. and how or where to look? Factory alarm?

Any help would be great.http://forums.pelicanparts.com/uploa...1255545265.jpg

Check your DME relay. It's a know source of trouble as you describe. The unit is the size of a standard square relay, only twice as tall.
We always carry a spare just in case.

Welcome to the board and good luck!

Oops! Forgot to mention it's under the drver's seat right next to your DME control unit (big square silver box).

you should hear the fuel pump running with the key in position 2. Some will claim its not supposed to, but it always does, at least on the SCs.

Id check the fuses and make sure you have none blown. located under the front hood.

good luck

Looks like you found your problem!

The relay switch is between the silver box in the centre of your picture( the main control) and the bell like metal dome in from of that. As you can see from the pic you posted its missing. The connector is connected to nothing

magnuskgc 10-16-2009 10:20 AM

thought that was the powe seat connector... The DME plugs in there??

twistoffat 10-16-2009 10:44 AM

The large silver box is the DME control module and the metallic circle is the altitiude sensor. Whats missing between is the main fuel pump relay. Thats what the plug is for.

It's alive!! thank you all so much for the info... amazing how much easier it is to get the car to start with a DME relay plugged in where it should be!

Thanks allot guys,

DME relays are the weak links on the 3.2. Always carry a known good one for a spare.

Congrats, the cheap and easy fixes are always the best.

poor guy , first factory ran low on roofs and needed to hit production numbers and sent any way , also must be the cabriohoodless or factory ran out and someone stole the dme ...


best of luck ... :cool:

DRACO A5OG 10-21-2009 11:21 PM

Well, now you discovered the Ghetto kill switch. Remove relay and car will not be stolen.

Unfortunately can be towed though.

Glad it was an easy fix.

theiceman 10-22-2009 02:03 PM

with his luck the theif will have a DME relay in his pocket ..

magnuskgc 10-22-2009 04:16 PM

yes that would be my luck..... but thanks for all of the help guys
