ok so my water pump seal goes out. time to change it. little did i know what was instore for me. any way after replacing the pump, housing and lower radiator hose (just cause it was easy to reach) my car wont start. at first i thought it was just flooded (easy enough to fix) after doing the fuse trick nothing happend just spun no turing over. so i try the big flood fix with some new sparkplugs... still nothing. i think somthing is wrong with my coil packs b/c when it did the ohm test i got -08.0 for the leading and -7.9 for both the trailing coils. even took the plug out and held it near the intake manifold while a friend tried to start the car... still no spark

please help not driving my 7 for this long is making me crazy

Have you actually checked for spark? I mean run through the basics... is there spark, is there fuel?

The Blue Bomber 07-16-2002 02:30 PM

how should i check for spark and as for fuel well i can smell it

phinsup 07-16-2002 02:35 PM

Spark is easy, pull a plug ground it out, turn the motor over and watch for spark. Fuel... to start, pull the fuel line where it goes into the side of the engine (drivers side) and again turn the engine over and watch for fuel to come flying out.

What year is the car? My guess is that you knocked something loose when you did the job. That's the only explanation.

Did you connect the plastic tube that goes from the air cleaner to the throttle body nice and tight ? Even the nuts that go to the throttle body from that tube?

pengaru 07-16-2002 06:36 PM

I experienced a similar problem, replaced the wires, unflooded the engine, cleaned the plugs, car started and ran. But my coils has the correct resistance when tested.

If you can smell fuel, you probably still have it flooded. I hooked my car up to some jumper cables and turned it over for a good 10-15 minutes with the inj. fuse pulled before putting the fuse back in. First attempt to start with the fuse in and flames shot out the back burning all the fuel that had accumulated in the exhaust system. A timing light can also be useful for detecting spark, but if you have good wires like magnecor's an inductive light probably won't sense any spark.

this is the best way to check for spark. hold the end of the spark plug wire while someone tries to start the car. it works really well

horn4858 07-16-2002 07:27 PM

yea that can kill some people

horn4858 07-16-2002 07:46 PM

Rotaryman88 07-16-2002 07:46 PM

Now I don't feel as dumb...so far everybody has suggested stuff I thought of too...I think I might be actually learning more about ignition, lol. I should be in the chat room later tonight(11pmEST) if you need to talk some more blue13omber.

Just stick your finger in the coil. I've done that.http://www.plauder-smilies.com/smhair2.gif

hey guys finally fixed it. turn out i was putting the fuse back into the wrong slot (they arent labeled on my car) :ph34r: boy i feel like a dumba$$. once i got spark again (thanks to graham, my little brother, for detecting this for me https://www.nopistons.com/forums/pub...IR ) i did the atf trick and pop started my car (the battery was real low by this time) and it ran https://www.nopistons.com/forums/pub...#>/biggrin.png
