87 K5 was running yesterday this morning went to leave and dome light, headlights, check engine light and fuel pump arent working.


It has to do with the secondary air intake. first check for any cracks or leaks in the air intake system. most cars have a plastic routing tube that cracks or gets a hole in it from friction . could be even a bad clamp.check these places first. you might want to disassemble the whole air intake hose apparatus so you can really see whats going on on the bottom side.good luck ,and give me a rating if it helps,Gary

Running rough


A blinking or flashing check engine light indicate misfiring. I suggest you check the components of your secondary ignition system especially if it worsens when it's damp.

Check engine light is flashing while driving. It seems to be running a little rough. This just happened this morning when I started the car.


The check engine lamp will flash when the computer/emission system sees a problem that could possibly damage the catalytic converter or other components. Often the cause is a cylinder or cylinders that are misfiring which will make the engine run rough. Because the light has been flashing you should have the problem checked out and repaired to avoid any possible damage. Good luck, hope this helps!

2000 silverado 4.3 V6. Replaced feul pump and niw it starts but it takes 3-4 cranks in the morn to start it and then it runs very rough untill it has ran for 1/2 to 1 hr. Also have replace fuel filter...


The rough running should have caused the check engine light to come on. It would be a good idea to goa ahead and scan the engine for trouble codes. The rough running could be a number of things. The codes would help us pinpoint the correct part ot replace, rather than start replacing parts until we get lucky and hit the right one. That could be very expensive.

Engine light is blinking and the car runs rough,not enough power.


You shouldn't have taken the car back,nor should the shop given you the vehicle,if you were willing to have it properly repaired.
The MIL Light is an indication of an issue or two and you said it runs rough and has no power. What more does a shop need. Repair it.

Is the Fuel Filter fairly new
Did they Clean the MAF Sensor,and make sure your air filter cover is on correctly,and you have no vacuum leaks.
They can look at all sensor data and resolve this ,if they wanted to.

Service Engine Light has been on for a few weeks


A blinking SES means a catalyst destructive issue is active. If the engine is running rough it may be due to a missfire, I would have the codes checked to see what codes are active and that will give a place to start with a diagnosis. By the way the oil change will surely not hurt anything, it is just very remote that it will rectify the blinking SES. Good luck.

Engine turns over fine , car will not start.


well the first part of your question i was all ready to tell you to put a new fuel pump in, now not so sure, there is a relay for fuel pump, can you hear pump cycle and relay click? relay under hood you will have to listen close they don't run long maybe a couple secounds, if you don't relay bad. if you do pump could be bad, do fuel pressure test pump could be weak. don't think sunroof and turn signals are related, but stranger things have happend.

Kia problem


You should get the codes checked and start from there. My Kia Sportage was also backfiring and running rough, after checking the codes. It had misfires on two cylinders. I did a tune up and had to replace one of the ignition coils. Now it runs great!

Runs rough when cold


On start (Especially in Cold temperatures)it is harder for the oil pump to bring oil to the top of the engine,making noise more prevalent .Keep fluids level and oil clean and you shouldn't have to worry.
