I have a 2010 jeep grand cherokee 3.7L 77,000 miles. It was throwing a misfire on cylinder 5, so we changed spark plugs. New spark plugs in and jeep will crank but never start. What now?

Asked by atown502 Aug 05, 2015 at 09:06 PM about the 2010 Jeep Grand Cherokee

Question type: Maintenance & Repair

Yes we tested for spark and fuel-both
present. Checked all fuses- they are all
good. Triple checked spark plugs- they are
correct replacement NFL plugs. We also
reset ECU. Starter has good clean
connections and new battery installed.
Next route?
Control module? Key FOB? And how do I
test these 2? Any other suggestions?

1994 Jeep Grand Cherokee will run and then just stop. There is no spark to teh spark plugs. When it cools down it starts up again. We have changed teh collnoid and the crank shaft sensor. 2 Answers

When driving the motor just quits. It will go a couple of miles then quit. We have changed the colloid and the crankshaft sensor and it still does the same thing.

Bought a 2004 jeep grand cherokee with 109,000 miles on it. Everything worked and ran great on test drive. After driving it 3 times over a week the battery died. It was a newer battery and checked out fine. Put a new alternator in still would not always start. Put a new starter in ran for two day and now will not start again. Short somewhere? Where to start looking. Does have an aftermarket remote starter hooked up, have not used that yet. 1 Answer
