Aim: To get the car running again
Required: 10mm socket, ratchet to suit, solder, soldering iron, flat head screw driver.
Steps: not many


so your car starts fine, but after some driving it will stall and wont restart, or restart then stall again, this can be symptoms of the Main PGMFI Relay at fault, as well as other things like coil, ICM, but since the main relay is so easy to fix, why not start there.

A good sign of the relay at fault is you might not hear the fuel pump prime for 5 seconds when you 1st turn on the IGN, ( it can still prime if the relay is faulty )
also low or no fuel pressure.

STEP 1: Locate the main PGMFI relay, you will find it under the dash, commonly the RHS but donít be fooled, lots of models have them on the LHS, CRV for example you have to remove the glove box. The relay looks like this





STEP 2: remove the relay, there will be one bolt with a 10mm head. Unplug the wiring harness.

Step 3: open the main relay, use a flat head screw driver to pry it open, do this evenly from both sides.






Step 4: look for the dry solder joint, if you cant see it just reflow the solder on all the joins, add solder but not to much, allow the solder to melt and bond to the components. Reflow the solder on every join, only takes 5 minutes.





STEP 5: reassemble the relay in reveres to disassembly and refit to the vehicle.

Thatís it !!!



If you have fixed your relay and still have problems of not starting, start looking at your distributor, e.g. ICM, Coil. Also the ignition switch
