Question about 1998 Jeep Grand Cherokee

98 jeep grand cherokee 5.2 hard to start

The first start and after the car sits for an hour,it takes along time to start and when it does it runs roughly for a few seconds. I found if I turn the key on and let it on, without starting the engine for about 10 seconds, it will start up right away. After it's running it runs good!

Something is going on with the fuel system bleeding down.
there's a small leak somewhere..take it to a shop and have them look at it. Could be in a number of areas but with hands on they'll be able to help you out.

Sounds like fuel flooding the carburettor.
I would check the air filter is not dirty as this can cause more fuel to get sucked into the carburettor and use a lot of fuel, once you stop the car it has excess fuel in the carburettor then after sitting for a little the excess fuel evaporates.
I would start here as cheap fix just an air filter then look at the fuel filter and spark plugs.
Hope this helps.
Regards Craig

2005 chevy silverado 1500. Just on first start or if sits for a few hours engine will bog down. When using auto start takes a few tries


Possible fuel pump issue causing fuel to drain back into the tank. Check valve inside pump may be bad. Once vehicle is turned on it may take a few seconds to prime up the fuel lines until operating pressure is reached. Put a pressure guage on the fuel rail and start the vehicle. Should be approx 55-60lbs running. Turn off vehicle and leave it sit with guage attached and monitor for pressure dropping off to 0. If so, suspect a bad pump

If my jag has been sitting for more than 24 hours the first time I try to start the engine takes maybe 8 or 9 cranks before it will start, after this she starts quickly.


Sounds like the engine oil is quite thick when cold so you probably need to check the last time the oil was changed along with the filter.once it gets slightly warm the engine takes less cranking amps to turn over so it will start quicker.

My 1994 Jeep Grand Cherokee with the 5.2L is very difficult to start if it has not been run in the previous 6 hours. Replaced ignition coil but didn't solve the problem. After sitting overnight it


Low fuel pressure.
You need to check the fuel pressure on the first crank and watch it as it is running.
Requires a special gauge.
If it were just a starting problem I would say it could be a pump relay, but not if it runs rough for 5 min.
Might be a dirty filter or problem in the tank.

it could be a bad fuel pressure regulator. or a blocked fuel filter. heres the regulator symtoms. the vehicle runs rough, the engine will not start ( usually in the morning )many times engine starts but stalls shortly after starting. a bad regulator can result in fowled spark plugs, replacement is only cure. ( black soot on plugs, blake smoke from tail pipe, running rough and stalling. check fuel filter first.

Slow to start after sitting a few hours. Engine turns over fast but takes several seconds to start. once started, subsequent starts are good until you wait a few hours.


Check the fuel system pressure--if low, a weak fuel pump may take some amount of time to restore sufficient pressure to start. Does the exhaust emit black smoke for a short time when having starting trouble? This could point to leaking fuel injector(s). Don't know whether doing a computer scan would show anything, but maybe worthwhile. Go to Autozone or similar business for a free scan. Hope this helps!

I have a 96 S-10 Blazer, Does not want to start


Replace the fuel filter to help the fuel pump, but it sounds like the fuel pump check valve has gone bad and your losing your fuel pressure to start the engine. Your going to have to keep priming the fuel system by turning the ignition key to the run position for 5 seconds 3 times before you try to start the engine. The only fix for this is to replace the fuel pump, and that is costly. Good luck and take note: the fuel pump has a life time of around 150,000 miles and anything past that is borrowed time.
