Not having a wiring diagram, I can say this sounds very much like a grounding problem to me. Try running ground wires to the headlight buckets,bulbs an Ignition module.

Also check the charging and bat situation as most solid state igs require a minimum of 9 vt.

Don't miss the key switch output.

Engine shuts down,loose of power,replaced battery,altornator...2nd battery held charge.stills dies out when I drive..will the key switch solve this problem


Is the battery / charge light lit on the instrument cluster ? Did you have the charging system tested , they'll do that for free at auto parts store ! Do you have battery voltage at the bigger wire at the back of the alternator ? This wire supply's the current to charge the battery ! The smaller wire in the connector supply's voltage to turn the alternator on. Your running down your battery that's why it shuts down . It's not the key switch . If no battery voltage on the bigger wire ,check fusible link at the battery ! all so check gauges fuse in the instrument fuse block it is a 10amp fuse . Do you have the battery symbol light , light up when you turn the key on ?

I have a 2006 Impala 118844 miles. engine power reduced light oil pressure low shut engine down starting disabled service throttle I have oil leak oil is full though.. Car drove this morning then shut off...


Your fuel pump power is controlled through the oil pressure switch, and if it is showing low pressure due to a leaking/defective oil pressure switch, it may shut off the fuel pump. Oil pressure switch failures are a common source for oil leaks. There could, and probably are, other issues going on. You never mentioned if the "check engine" light was on, and if it is, a scan would definitely be in order to determine the true cause of your problem
If it is not on, GM fuel pump failures are very common, as well as the vehicle security system my be having a programming issue. I would start by having the engine scanned (most Autozone locations do this for no charge) Good luck!

Cruise control won't switch on - light on dash switch not on - could it be a fuse? and how do I find it?


look in engine bay for cruis control actuator it will have a wired cable connecting to the accelerator throttle in the engine bay follow it back to find unit. Check for any electrical plugs that may be loose. Check also the brake Switch above the brake pedal as the cruise control should have a tap on to the wires if this switch. if the wires come loose the cruise control may shut down. Also follow the wires on the actuator see if any fuses connected to them.

Electrical problem for the fuel no power


A lot of newer vehicles have a fuel pump cutout switch on the engine. If the engine shuts down for any abnormal reason, it loses oil pressure and one of the things that happens is the fuel pump is cutoff. This is a safety item in case of an accident which shuts off the engine. Check for the oil pressure cutout switch on the engine, which is usually different from the oil pressure gauge or light switch. Can't say exactly where it is, sometimes on the upper rear part of the engine behind intake manifold or on lower side of engine right into the block. The fuel pump run circuit is different from the fuel gauge circuit although they usually run in the same wiring harness if the fuel pump is in the tank. If the pump is not in the tank then the fuel level sender in the tank is probably defective and should be replaced.

Is it normal for the dash lights to come on when you shut off the engine 95 regal 3.8


I'm guessing your battery charge lamp and oil pressure lamp are coming on when you shut down the engine. This is perfectly normal because your battery is no longer charging and your oil pressure is down because your engine isn't running. If however you've switched the ignition off and these lights appear briefly while the engine is stalling, the fault is either a diode in the alternator, or a wiring fault within the dash display. Hope that helps.

2002 f350 will not shut off with key. with key removed dash lights stay on and engine continues to run must pull injector relay to shut down. the dash lights stay on as if you turned the key to accesory...


ok well this is where you might be incorrect... either you have a 12 volt wire bleeding scross or you have a bad ignition switch. the run wire off the ignition switch is the only thing that will keep it running unless you have a remote start then of course that could keep the engine running. you might want to start by making sure the ignition switch is beaking the signal to the PCM.

What will cause a truck to lose all oil pressure and the engine to shut off while driving down the road?


If wires came off oil pressure switch or if switch went bad, it would shut down truck immediately. Your oil pressure switch performs 2 functions; oil pressure to gauge.light and it's also a safety feature that if you're in an accident or rollover, when oil pressure drops it shuts off power to fuel pump. I'd start there. The reverse is also a possibility, if fuel pump fails, truck shuts down = no oil pressure.

Set timming


You will need a timing light for Hi energy ignition as well as standard socket set or wrenches. 1. get the engine up to operating temp. 2 shut off engine connect the timing light to the number one[1] spark plug wire at the spark plug end connect battery connectors. 3 start engine and note location of pointer on the mark tab on the timing cover. 4 shut off engine loosen the hold down clamp on the distributor turn the bolt no more than one full turn[snug is better than loose here] then note the position of the dist. cap. Move the dist. to make sure it moves freely replace back to the starting position and remove and plug the vaccum line to the dist. 5 start engine and set timing to the desired spec. 6 shut off engine tighten dist. clamp bolt 7 start engine check timing one more time to see if still there at desired setting. 8 shut off engine dis-connect all tools and light

1996 NISSAN MAXIMA SHUTS DOWN FOR 1 FULL SECOND!!!


It sounds like your car has an intermittent open current feed problem. Has there been any electrical/component repair or replacement recently? If so, that would be a starting point for diagnosis. Sounds like an ignition switch type problem. If you had an intermittent battery connection, the car would continue to run from the alternator output, but would not cause the warning lights to go through their initial "bulb check" sequence. But if "on" voltage is lost at the ignition switch, or that circuit, it would.
