The way you are saying it sounds like the alternator is going bad which will directly affect the ignition sys, being an old vehcle i would suspect the fuel pump shorting out

All the above problems were happening to my truck, and the engine light never did come on. Finally changed the O2 sensor, and it runs like new again.

Mitsubishi lancer glx 2005 wont start no power on fuel pump and no spark


Before you do anything else find the fuse box and check for any relays or fuse blown. then check fuel pump itself by putting direct power from battery to see whether is working or not if not renew fuel pump. If you have no spark and any relay or fuse is not the cause,the go for distributor electronic module bad contacts,or finally ECU or Immobilizer.

I have a 2002 ford escape with about 170,000kms. From a cold start she runs perfect. But when i make a stop and park for a short period of time then go to leave is the prob. Starting up is no problem but...


Misfire, From a cold engine you wont have the misfire. When you engine is cold fuel is in demand and it will run great. As it warms up the fuel strategy is to lean it out (proper balance is 14.1 to 1) . At normal operating temperature the spark plug required KV is 15kv. As you accelerate the sparkplug require more voltage from its coil reserve and it delivers and at the same time the engine demads are high in order to accelerate and the spark will seek the easiest path spark plug, now when you come to a stop the demands for spark decrease and it seek the easiest path where is that at ? out through the boot of the spark plug, The vehicle is equipt with what they call COP (coil on plug) along the boot path it deteriates and so does the coil it deteriates .170,000 mile of hard working COP. they are at their worn stage you can find the weak coil with a cop tool because it misfire on acceration your looking at a boot,probable water got in there shorting it out,if it misses at idle its either water in the boot or the boot itself or the cop.

Fuel pump not working


check your fuel pump relay,under hood in black box. main fuse box. either on driver side,passenger side.lift the cover off,under the lid you should see locations of fuses and relays. try replacing your fuel pump relay 1st then if no help,check all fuses for blown ecm fuse or blown main engine fuse. when yu turn your key to on position, can you hear your fuel pump hum? this will take 2 people but have to be sure. while someones laying on ground with their hand on your gas tank, turn key to 'on' position. they will hear or feel the fuel pump hum. try to narrow the field,is getting no fuel? is getting no spark? this means alot when trying to diagnose.i get frustrated sometimes myself because if i were there,you would know whats up. thank you for choosing fixya.com i look forward to assisting you in the future.

Vehicle stalled on road-towed in-timing belt had missing teeth-fuel pump had no power--replaced belt-have good compresion-still have no power at fuel pump connector and no spark


Hi,
Sounds like ECU problem.
First, check your fuse box if there are some blown fuse and replace it. If there are no blown fuse the problem would be the ecu computer.
The best advise would be to bring the car to your nearest dealer and have their computer analyzer check your ecu. Thus you will have save time and money from guessing the problem of ignition and power supply of the fuel pump.
Hope tat helps you out!
thanks for using Fixya!

90 corolla efi problem?


Classic fuel pump failure, Efi fuse runs the fuel pump now its open and it won't start. With it cranking and not starting add a little fuel to the air inlet and if it (flashes off ) ( runs a few seconds ) there's no fuel and the fuel pump is the most common cause. The pump is in the tank and unles s you feel that you as good as any pro mechanic and have the experience then let a pro do the work as the danger is high even for a pro.

Wont start has spark and fule


check the fuse box under the hood and make sure the fuel pump fuse is not blown.
if the fuse is blown, replace it and see if you have any fuel/spark. the fuel pump fuse controls almost everything electrical under the hood. if the fuse keeps blowing, then there is a short sumwhere in the engine wiring harness.
