2009 joyner trooper

[dmdc]

NEED HELP - i have a 2009 trooper Joyner. the vehicle has a no start condition. no spark or fuel

after changing starter for possible bad soliniod vehicle will not start

there is no spark to the at the sparkplug and the three wire coil wire harness connector has 11.5 volts at each wire

in addition with the ignition switch at KOEO the fuel pump and cooling fan to not operate...no power to the fuel pump.. when the fuel pump is provided 12v directly from battery the pump and fan operate. the fuel switch is broken but had been bypassed and has 12v on both sides

all fuses and relays are in good condition. all fluids at good. battery charged. compression is even on all cylinders

also i can not locate the ALDL connector, it is not in the passenger side glove box area, any suggestions

i have owners manual but it dose not address a no start condition like this.

need help thank you

was everything working prior to removing starter? is the starter cranking it properly now that you ve changed it? all wires were correctly hooked back up to starter? ..Im not sure what you mean by "fuel switch" ?? maybe main power shutoff??? if the fuel pump and fan are not cycling when you first turn the key to start/run position..and the starter cranks properly..I would start with there being a power/wiring connection problem in the fuse panel behind the drivers seat ..also check ground connections normally found on transmission housing bolt below starter...Hardy

sounds like you need to look at the wiring to all you relays. look for hot connectors and burnt wires on the back side of the relay sockets.

my 08 has no ALDL connector, not sure about 09s

Have you got a manual for your Trooper, read part and pieces, it'll tell where to down load one.

thank you for all your assistance.

i am unsure of the condition prior to this post as i received the vehicle in this condition after repairs had been made. i have the manual, but i just got stuck. i did a visual inspection and found no damage to wiring or fuse block. i will check fuse block and grounds with DVOM next time i work on vehicle

i suspect the ECU may have been damaged or i am not getting crank shaft signal to trigger spark/fuel. does any one have a test for ECU or no how to pull codes from this thing?

Thank you again for all your help

compared to electrical connection problems,ecu rarely has/is the problem burnt or melted wires ..corrosion (inside fuse box and/or in wiring harness plug connections) wiring harness damage,and bad grounds..all quite common as most machines typically were not gone over and well sealed from new...these problems are much more common than a failed component on the trooper..not to say that nothing ever fails,generally if fan and pump are not receiving power to cycle on start up,means ecu is not getting power...just my 3 cents...Hardy

Also, unless the plastic around the fuse melted or around the base where the relays plug in, a visual check may not reveal the burned wire or the hot spade lug connector that goes to he relay plug, I've seen them still together, but not contacting, pull the fuse relay block that's behind the seat and take a look there. That's where the pump and fan are common and the power for the ecu

PS, fill out your profile so we know more about you and where you are, you may have some one just around the corner who can help and may go ride with

dmdc...how did you make out...agreed with Kinarfi as to unbolting fuse block and looking/testing inside as have also found corroded and melted wires and connections on the back side...once repairs are made, recommend try to seal up (weatherproof) fuse box best you can ...Hardy
