I have no spark or power to the fp

[Joses95TSI]

Ok i have no spark on the my tsi .I alredy check the coil and it pass the the test i did so then i check the power transistor with 1.5v battery,digital ohm meter,a light bulb. And when i put the eligater clips on pins 3 and 8 to check coil 1/4 i get continuity flow and the book saids i shouldnt get any until i put the 1.5v battery on pin 7 and 3.And when i put the battery on pin 3/7 i get a higher continuity flow.So i thought i do it with the light bulb and i still get the same results.And the same goes for coil2/3 those that mean my transistor is bad or at my doing some thing wrong.I check my wires and plugs and they all seem to be good.And my second question is why at my not geeting any power to the fuel pump even after i rewire it.My pump runs when i just hook it up directly to the battery could the transistor have some thing to do with it.Please help me is been almost a year with this problem but never gat around to fix till now

Just because i've been in the same similar situation but this may not be your problem, it could be your ecu capacitors finally gave up and the ecu needs replaced/repaired. Most likely if it is your ecu and the caps exploded it'll just need replaced.
There are many things you can do to check for the ecu being bad without taking it out, an easy one is first make sure you've got everything you've been disconnecting and such put back the way it is and the insert key and turn all the way but don't try to start it. If the stock boost gauge goes to 0, (above vac), then that's a good sign. There should be a little 'tick' you hear when you turn the key all the way over but not starting it as well, that's the mpi fuel relay. If you don't hear a tick then the relay isn't coming on, also a sign the ecu is dead or perhaps the relay is toast or something in the system is busted.
You have a 2g so I may be wrong on the above advice I just know those things work for my 1g. I would assume you still have ecu failing issues and an mpi relay.
Also make sure you check all your fuses.
Just things I thought I would offer to you as advice.

Thanks.So you dont think is the power transistor because i took it out and it fail the test i did.But i well put everything together and do what you said thanks again.

have you tried to connect a battery/jump box str8 to the fuel pump itself? another thing that comes to mind is the MPI relay underneath the center console( behind the radio type deal ). also make sure all connections on the pump itself are good.

had this issue a while back and it seemed to be a simple mistake i had made. so just go through all the wires best u can and make sure thats not causing it to get any power. just a suggestion

Plugging power straight to the fuel pump is fine and I guess will tell you the fuel pump is working, but (correct my if i'm wrong somebody), I'm pretty sure the mpi relay won't come on if the fuel pump is dead. But hooking power straight to the fuel pump will tell you whether or not it's a ecu/mpi combo issue or possible mpi/fuel pump combo issue. (That's if the mpi relay won't come on if fuel pump is dead).

The little tick I spoke of previously is easy enough of a test though for a first test, that's my starting point for whenever I had fuel/spark issues and I think it's something electrical.

Good luck,
Brian

Also just a thought, I found my old thread from when I had ecu issues and not getting spark etc. http://www.dsmtuners.com/forums/showthread.php?t=223888 it has some diagrams I made of the mpi fuel relay that you can use to test your relay to see if it's functional. If you don't get a click that I told you to listen to it could be that the relay itself is bad, and if you don't have the money to just buy a new one or would rather test it first the diagrams should help.

Ok heres what i have done so far i change the fuel pump and still not getting power to it.So i put straight power to the pump and crank it 1 or 3 times and nothing so then i check to see if i had spark and come to find out i did not have any on iether coil so i take the coils,transistor out of the car and check them so far the coils check out ok but the transistor didnt i had power going even with out the 1.5v battery.So i order one from ebay for about 45.00 and now just waiting for it so if i get spark then i well check the relay/ecu by the way what is MPI is that the fuel pump relay and also is the fuel pump relay blue/black or solid black because the ones i found behind the radio where blue/black and a solid lack and thanks for the help guys.

The 95 has the fuel pump and MPI (multi-port injection) relays both in the same box. The PT sounds like it's the problem (try this test if you haven't: http://www.dsmtuners.com/forums/showthread.php?t=229419).

You must have ignition before the ECU will turn the fuel pump on. It also must be either cranking or running. Just key "on" but engine not rotating will not turn the fuel pump on.

So it is not like other cars right.I asked because my friend has a 93 ford probe gt and when he turns the key to acc NOT CRANKING OR ENGINE RUNNING the fuel pump comes on and pimes for about 2 seconds and then it goes out.So thats why i thought maybe the talons where like that.But you said the pump only comes on when cranking or running right luv2rallye.Ok so right now iam just waiting for the transistor to see if i get spark and then i well move on to the fuel system thanks guys for all your help i well let you guys know what happens after i install the transistor.
