      Hey guys i've been stuck without my jetta for about a week and can't seem to find the issue. I hooked a multimeter to the fuel pump and when my key is turned my fuel pump doesn't turn on. When i push start my car the pump has power and runs good. Could this be the fuel pump relay?

      My check ENG light is on when I turn the key so its not my ECU, Also I tested the fuel pump voltage after poping the clutch to start it and it gets 12v. BTW its a 97 jetta GL 2.0 aba 5 speed.

      Ignition switch. Try it post back.

      Hey guys, I changed my Ignition switch today and still no power to the fuel pump when the ignition is turned on.

      So far i've changed the following:
      Crankshaft Sensor
      Distributor Cap/Rotor
      Ignition Switch

      Any other suggestions guys? I'd hate to have to scrap the thing, its so fun to drive.

      Now I could feel safe saying change the relay #167.

      Actually I changed that as well, but forgot to list it. Fuel pump relay right?

      Just to clear things up. You are unplugging the connector to the Fuel pump and measuring Voltage. You have no voltage with the Key on/Engine off?

      But when you bump start it, you have 12v to the pump?

      Very odd. it is almost like your power wire to the fuel pump is only live when the alternator is pumping out voltage. Something is wrong with your Wiring possibly. I would definitely trace the circuit very carefully to rule out any problems such as a frayed wire or bad ground.

      Yeah that's exactly whats going on, and yeah i will have to check the wiring out with a multimeter, but its weird because when its bump started it runs good.

      My car did not have power to the fuel pump with the key in the "on" position and had me tracing wires and all sorts of nonsense. Then I checked it while cranking and sure enough it has proper voltage.

      Yeah I've checked it while its cranking still nothing, any other suggestions? We put starting fluid to it and it wouldn't start so I'm thinking its something more than some faulty wiring.

      So i noticed today while cranking the starter that my fuel pump relay is clicking rapidly when the key is turned. Anyone else run into this problem?

    12. 07-18-2012 02:08 AM #12
      Seems to be a pretty common issue, I ran into it myself. We back probed it and got schematics. Replaced relays, pumps, tried with different chip in ecu and nothing. We narrowed it down to a possible broken wire from ecu to fuse box, Some sort of grounding wire was broken somewhere along the line. Simple fix for me was to wire in a switch to manually controll the pump. When starting the car I could flick the switch on to get fuel to the motor and when it fired I turned the switch off. After that never had a problem with mapping or burning out the pump or anything like that. Be sure to always turn the switch off if you do take that route

      I took it to a shop today that does foreign cars, they told me that my distributor was bad. I have a new one and am having it installed tomorrow, ill let you know if its the problem.

      I don't think the shop knows what they're talking about.

      If you scan the engine not running, you always get a engine speed sensor fault, and a cam position sensor fault. The engine does not even need the cam sensor to start and run (on a car that is working properly, you can unplug the cam sensor, and the engine will still start and run), the ECU will run a default setting.

      There are two different circuits that power the fuel pump. One is activated when you turn the key to the "START" position (bad ignition switch or ignition switch start wiring and the car will not power the fuel pump when the key is turned to "START". When you let go of the key, and the ignition switch drops down to the RUN position, the fuel pump is run off the ECU, and relies on sparkplugs impulses (no pulses to the sparkplugs means no fuel pump power).

      Well they had the car start with the ignition 4 times while they were diagnosing it and apparently they were tapping on the distributor cap.

      im still fighting with the same problem myself so far ive replaced the wiring from the bay to the fuse box, fuel pump, distributor, coil, cap and rotor, plugs and wires, Ignition switch, ecu, fuel rail and injectors, and the crank sensor. replacing everything listed hasnt helped me. hopefully one of us can get it figured out.

      How did you go about putting that switch into your fuel pump ObeyJettamk3 ?

      Yeah hopefully we can figure out a solution. I'm going to take it back to the shop that looked at it and have them look it over again. I'll let you know if there is any good news.

      Sounds good man, I plan on going down tomorrow and having the shop look it over again. I'll let you know if there is any headway

      I'm having the same issue except mine wont push start and even when I installed a pump switch it still wouldn't turn over... I replaced the relays and no luck and I'm waiting on an ecu... I'm hoping that resolves the issue...

      Have you tried replacing your relay with a jumper wire ?

      No not yet, I'm not 100% sure on how to jump a relay.

    29. 07-23-2012 05:31 PM #29
      try the 20 amp fuse on the left side of the fuse block

      You make a jumper wire about 3 inches long with a spade connector on each end, then you remove your relay and put the jumper wire in to where the 2 large spades of the relay plug in. Your fuel pump should run continually when you do this.

      Jumped the relay and i heard my fuel pump turn. Still wont start with the ignition just cranks and wont fire. Any suggestions? I'm thinking maybe my ecu is shot but the light comes on with the ignition so I'm not sure.

      I'm also thinking maybe my ECT is bad or my EGR valve is stuck open or something, because when the car is bump started it sort of idles a little funky.

      Did the ecu fix your problem ddavis?
