WTF??? Engine Failure?!?!

[gjh20]

So i'm driving home, cruising at about 85mph, and all of a sudden i lose all power from the engine! all electrical items continued to work fine. when i try to start the car it will turn over very vigorously but never catch. to my novice ears it sounds like the engine is not getting fuel. however, i honestly have no idea where to start searching for the cause of this problem. a little background info....car is a 98 Q, 134k, has been exibiting all of the symptoms a few other y33 owners have been experiencing latey (jerky idle, hesitation, bad fuel mileage, tcs & slip lights randomly on/off, no chk engine codes being triggered). otherwise, i have no known probs with the car. i use synthetic oil, occasionally bg44k, & QuikTrip premium fuel. help me out guys, i really don't wana throw any misguided money at this problem. thanks

Drop it off at S. Cobb T3 and we'll have a look see.

On my 93, it was the crankshaft position sensor. Twice.

[Q45tech]

1997 Q41 and later use a different method of timing sensing than 90-96Q45.

Was it a real CAS faiult or a failure to clean corrsion and maintain connectors and sockets [AKA harness] feeding CAS?

Your car is ruined, it's essentially worthless now. You should probably just junk it-just so happens that I'm in Atlanta and I'll pay you $100 more than the junkyard does.Let me know,Andy

How old is your alternator? Mine acted the same when my alternator was bad. just a thought.

[gjh20]

I'M A JERK!!! i felt the need to preface my post with that remark. well, i replaced my fuel pump to no avail. then i checked the fuel pump fuse, only to find that it was blown. i checked it initially (i thought), but i replaced the wrong one. OR...it blew during the pump replacement process (which is totally possible since it was my 1st pump swap). so here are my takeaways from this experience, #1, triple check fuses before replacing parts, #2, replace parts correctly! thanks for all the help/suggestions guys. see you at NOPI

Good news! Have fun at NOPI.

SO - has the jerking and bucking stopped?

[gjh20]

unfortunately, no. still have "the skip". once i installed the fuel pump i ran a can of bg44k to make sure everything was clean and i still have the prob. we can definitely scratch fuel pump off the list of possible suspects...

*&@#*@&#*@&.. I'm going to start a game of musical coil

and.... GO!!!

[Q45tech]

Be careful to buy and use only new oem coils as we have tried aftermarket copies with dismal results.

We have seen a few Nissans come in with Napa [finally traced them back as being sold there and installed by another shop in another state] coils and codes, even non oem spark plugs react differently to as designed oems.

Good luck and happy swapping!

[beancan]

So - your actually suggesting the musical coils? .. It makes me feel daft inside doing it.. I'm going to get known good used OEM coil to play with

I love my q.. Love it so much I took out a seemingly BRAND new set of denso double platnim and replaced with OEM plugs..
