Hej, jag har lämnat in bilen för att den inte startar!
Startmotorn går men det kommer inget bränsle till motorn,
verkstaden påstår att det är relät till soppapumpen
men att dom inte hittar var det sitter!
Bilen är en C4 1995 cab!
Någon som kan berätta det för en oinvigd?

Det bör sitta under instrumentpanelen på passagerarsidan.. innanför säkringsdosan typ. lägg dej på golvet o ta en lampa o lys upp så finns där en massa skojiga saker =)

byt verkstad!

The fuel pump relay is located under the dash on the passenger side. You will have to remove the lower dash panel. Start by removing the air/heat vent by popping the center of the vent out and there will be two screws (Torques head) holding the vent in place, once the screws are removed the vent will pop out. Remove the side panel around and covering the fuses open and remove the fuse panel door you will see three screws that hold the side panel under the side panel there are two screws. After the side panel and the two screws are removed there are three nuts (10mm) where the air/heat vent was once removed the under dash panel can be removed carefully. Once the panel is loose disconnect the light and the panel can be set aside, you will see a small black box you will have to remove the cover and it does not tell you which one of the relays is the fuel pump relay.

Jag har pratat med olika verkstäder under dagen och fått olika svar,
under panelen på passagerarsidan så satt det tydligen typ 8 reläer?

Problemet med bilen är att det inte kommer soppa,
när man direktkör pumpen så funkar det klockrent
men dom tror på relät på verkstaden, har ni något annat förslag?

Har du kollat efter felkoder ?

-------------------------------------------------------------------------------

On a 94/95 you can check the codes with a paper clip as follows:

You short pin "12" to pin "4" and turn the ignition switch to "On" without starting the engine.

The speedometer will display any codes using the same protocol as the 1990-1993 model but there are some changes in the designation for the modules plus additional modules are added:

Module "1" is still the CCM module.

Module "4" is now called the PCM module (Powertrain Control Module) because automatic transmission computer control was added to Engine Control Module in 1994.

Module 7 (on the 1996 model only) is the RTD module. (This is the Real Time Dampening module which replaced the Selective Ride Control module in 1996).

Module 9 is the ABS/ASR module number from 1994 through 1996.
Finally, Module "A", the DERM (Dynamic Energy Control Module --- (the air bag control module) will be requested to show any codes.

Just like the 1990-1993 display, you read the codes on the speedometer (big) and read the module number on the trip odometer (small).

A series of dashed lines for instance “ - - -“ indicates no more stored codes for that module.

A code showing as “C12” for the CCM module (module #1) means no codes are stored. So C12 is a good thing to see.

Again, you can cause the codes to repeat by turning the ignition off for five seconds and then back on.

Turn the ignition off and remove the short to restore normal operation.

To clear the codes,

1. With ignition "off" ground terminal #12 of the DLC (use bent paper clip to connect pin 4 to pin 12)

2. Turn ignition "on".

3. Press trip/odo button on the DIC until 1.7 appears in the trip
monitor area of the instrument cluster.

4. Press eng/met button on the DIC & hold until "---" appears in the
speedometer area of the cluster, this will clear CCM DTC'S.


To clear PCM/ECM codes do the following:


1. Press the trip reset button on the DIC until the desired system is displayed. In this case it will be 4.0.

2. Press trip/odo button on the DIC until the desired diagnostic mode(4.7) is displayed on the trip monitor area of the cluster.

3. Press & hold the eng/met button on the DIC until "---" is
displayed in the speedometer area of the cluster, this will clear PCM codes.


To clear ABS/ASR codes do the following:

Same as above but you’re looking for “9.7” on the trip odo

Nu är detta min första vette, blir garanterat fler men var
sitter dessa stift som ska bryggas?

Jag är inte helt säker på -95:an men den bör sitta nere vid höger knä på förarsidan.

Kolla på den 16-poliga d-formade kontakten längre ner på denna länk

Okey!
Så då sätter man ett gem mellan stifft 4 och 12 och
slår på tändningen så borde man få felkoder då?

Ja , tala om vilka felkoder du får

Ska göra det, måste bara ta mig till verkstaden och se
om dom redan kollat felkoder eller inte!

Säkringen till soppapumpen var trasig, jag kollade bara säkringarna i motorutrymmet, satt ju säkringar inne i bilen oxå!
