i have a 91 tbi daytona . the other day i pulled into work and it just shut off .i tried to start it wouldnt . i got it home and messed with a few things . i put a new fuel pump and filter in i had and it still wont run . im getting no sparkand the fuel pump is not coming on . i ran a wire from the hot side of the battery back to the hot wire on the pump and it will come on . i changed out the fuel pump relay with another and nothing . what do u guys think it could be. code that are stored are 25,41,11,27 . the check engine light is not on now . i need this thing running by monday morning so i can get to work .

thanks

I would start with the 11 code. It basicly says no HEP signal. Fault Code 11 If the computer does not see a HEP signal it will not turn on the ASD relay and this would be why there is no spark or fuel pump running. Did you pull these codes after you hot wired the pump? If so disconnect the battery to reset the computer and crank it again. if the code 11 is there it isn't seeing the HEP work.

ok just disconnected the battery and now have 35 and 11 . so im going to buy a hep ? i checked it and it looks ok .but a new one is only 30$

new hep is in and i disconnected the battery while i changed it out . still no spark and now fuel pump . disconnected the battery for a 1/2 hour and pulled codes again still 11 and 35 . the rad relay was not pluged in when i was messin with it . i plugged it in before i installed the hep . hep is from advance auto and is new . i checked for spark after i changed hep .

^bad idea. Anything but mopar HEP's in my cars. There are a couple horror stories of people getting 5 aftermarket HEP's in a row and then ponying up the money and getting a mopar one and it worked great!
You should also be getting a disconnected the battery code too shouldn't you?

[turbo minivan]

you can get a HEP for 30$?? wow! there 90$ up here from a parts store! BRUTAL!!

[grim]

yes im getting code 12 and 55. ive read the storys about the mopar parts . advance had one in stock and i had to try something . i need the car monday and the dealer around here will rape u plus there not open on the weekends

[turbokid]

I realize they will rape you but the part is worth it!
If you need it to get to work monday then its the only way to go.
Too bad it's closed now.
You can get lucky sometimes on the aftermarket HEP
But you still can't rule out a bad HEP reliably using an aftermarket one

If it's an option at all, that's one of those parts you have to grab at a salvage yard anytime you see one. They usually get about $5.00 for them and with these cars, it's good to carry a spare. (Don't forget a good long phillips too)
Another thing with these cars is the wires going to the HEP get stressed from not being succured to the side of the distributer. I've had problems with the HEP, put in a new one and it didn't work. Threw the old one back in and it was fine. I even had one that would cut out taking a left turn too fast. That's one I never could figure out. The problem went away. That always sucks cause you never know when it'll come back. Wiggle the wires and reconnect the HEP before you going buying more parts.
Good luck.

in my opinion, u didn't need a new hep to begin with but u rookie troubleshooters attempt to solve probs by changing parts hoping to fix the prob instead of doing real diagnostics.

The blades shield the field producing the signal drop and triggering the spark from an amplified ground signal to the coil. It's a solid state device and rarely gives problems - Generally the associated wiring and connectors or ignition module are the causes of failure. You learn to carry an extra, and a phillips screwdriver, they do fail.
