Car started chugging on highway and at one point it just started shifting gears between 2nd & 3rd. Went to auto store hooked it on computer and it shows code P1671 ( Quad Driver Module b Quick set detected malfunction) after that turned car on went home and car kept doing the same thing, one hour later went to car and tried to turn car on and did not want to start. What can it be or what can I do cause its been a month and car has not turn on?

Have you checked, for spark yet?Also what about fuel pressure?If you hold your gas pedal all the way to the floor while trying to start it will it start?

Sorry for the delay, am handicap and sometimes is hard for me do thinks. Thank for your patience.
Well I check the spark on 1&4 and they have a spark, I don't know if u want me to check 2&3.
The person helping me said "if we have spark on 1&4 the crankshaft position sensor is good". We no check the fuel pressure with the proper gauge but when u push the valve came out fuel with rely power. My friend " the one helping me", call some vary else and tell him the problem we have on a car, " the same question I ask you in the begining", and what he said may be can be ignition coils or ignition control module because the same think happen in his car in the same way as me. The mechanic change his computer and the car doing the same, crank but no start, they have spark but the car crank no start, check the fuel pressure was ok, as soon they change de ignition control module the car start and run as never before he said. He have a pontiac 2000 sunfire. What do you think bout it? Can we belive on that?

Is it a nice blue spark you have?I would make sure you have spark on both coils?Also I would rule out the ignition module atleast for now. If you have spark on the on coil that means the crank shaft position sensor is working. You also need to check the actual fuel pressure not just it sprays fuel. Have you tried spraying some carb spray in the throttle body to see if it starts up?

Well 1&4 had more of a blue spark than 2&3 but did have spark so crank shaft should be ok, but didn't try spraying carb spray in throttle body, so guess I will try again tomorrow and will check fuel pressure
