Trilogy MM hit bump will not start HELP

[Command Car]

I hit a pothole last week, front left wheel went in. Although I was only going about 25mph, it was the kind that bottoms the suspension and rattles your fillings. No damage, but the car it would not start afterwards. I slipped it into neutral and tried the key while still rolling. Electric went on, but starter did nothing. After I rolled to a stop, I disconnected the battery, and reconnected. I turned the key a couple of times and after a few tries, it fired up. I drove about 1/4 mile and the car died. I checked the inertia switch in the trunk, but it was never activated or reset itself when the battery was disconnected.

I can get the starter to turn over with the key once every 5 0r 10 tries, but now the car will not start when turning over. It acts like it is not getting fuel and the key is not reliable anyway.

Looking for help with tracking the problem down. Please help. Thanks, CC

Did you try the inertia switch in the trunk?

If you read his post you'll see he did..... :shake:

[Bradley G]

The transmission position switch, or called neutral safety ?

[Joe Walsh]

Can you hear the fuel pump 'hum' when you turn the ignition on?
Check for fuel pressure at the fuel rail's schrader valve.

Is it an older Trilogy with a chip? If so, pull it out, clean the contacts and reinsert.

Yes, older Trilogy, I pulled the chip, wiped off the contacts and reinserted. No Joy. thanks

New Info: The key will not trip the solenoid, the fuel pump is not running. There are 12 volts at the ignition switch. Somewhere between the ig switch and engine compartment the voltage drops to 4 volts. Any guesses? Nasty wire or component failure???

Corroded wires / terminals at the starter

Check the wiring harness behind the drivers side cam cover. Known spot for wires rubbing / chafing.

Also check the relays in the Power Distribution Box under the hood an behind the battery.

[Comin' in Hot]

Check the lower fender braces in the wheel well, the harness runs past there on both sides I've seen a lot of chafing on a couple marauders

[Spectragod]

Chafing is generally bad...... The last one I dealt with was behind the driver side cam cover on the brace for the wiper cowl.

So what fixed this?

I was driving my marauder on the highway at about 65 mph, huge truck cut me off and I swerved right into a pothole as big as Texas

Front left wheel hit the hole, car shut off and red light on top of dash by the windshield went solid red for 1-2 seconds, then everything went back to normal

Runs and drives fine, new battery recently..... Somethings gotta be loose or it wouldn't have shut off and came back on

[Command Car]

Not fixed yet. I srill need to check the suggested spots. Thanks for adding your experience. It is relevant.

[Turbov6Bryan]

I will go over my car tomorrow and report back to you what I find out

Odd is I was doing like 65 or so, hit the bump and lost power on gauges, radio ect. Then it came back to life, I swear it died, or went from 2200 rpm to 500, but the tach was completely at zero

Gave it gas and nothing, figured it died, gave it gas again and back to normal

Never had to crank it over with the key....

Dropped off a few DVDs and started like normal, drives normal, somethings not right, I can just feel it

Right when it happened I thought of this thread, mine has a chip that plugs into the PCM, 201,500 miles and going
I've put 10k on it in 10 months :lol:
Hope you get yours sorted
Cheers

If the chips contacts are not thoroughly CLEAN, AND duct taped down really really snug into their slot the exact symptoms will happen. Frequently. I remember back when I had one..

Question, wouldn't it still start if the chip were just pulled out then? :dunno:
(I know I know do not drive it like that)

Should unless it screwed something up.

Had to close the garage door on this one for a while. I reopened today and took a look. Still not starting when key turned. Plugged in scanner, did not connect with chip in. Tried a second chip I have and scanner did not connect. Then tried the scanner without any chip in and it linked to the computer, showed no codes.

Then I tried to start the car with no trilogy chip. The dash lights went dead, the car continued to draw power (short) even after the key was turned off.

Help!

At this point, I'm wondering what the value of the car is with the trilogy kit, but with the wiring problem.

Any thoughts on fixing appreciated.

[WhatsUpDOHC]

Do you have a spare key?

Could it be the PATS?

[Zack]

What is the PATS light doing when you attempt to crank it?
Did you try starting it in neutral?

[Command Car]

tried both keys, pats light flashes slowly (normal?). then goes out when ig is turned to start.

[Turbov6Bryan]

What is battery voltage on the cables while you crank?

Sounds like a broken cell inside the battery

[justbob]

Not to keep beating a dead horse but I noticed you said you wiped the contacts of your chip clean. But did you remove the PCM and lightly scuff the contacts with a scotchbrite until shiny?

I had to do this twice in the short time I ran a chip for the exact same thing your going through.

What the heck? Where are you pulling 12 volts at the ign switch????

4 volts eh?

Might have multiple broken cells

Swap the battery

Tell me more about the car and some pics.

I'm interested.
