If the engine has to be turned over a number of times before starting it may be fuel pump related, more overly the check-valve within the fuel pump. If this has failed (or leaks back) the fuel system will need to come to pressure before the engine will start. I'd check your fuel line pressure when running you should see @ 40PSI or so; once shut down the system should hold pressure; if it drops off to zero then you know where the issues lyes.
I hope this may have helped.

Hyundai tuscon: petrol. after about a 100 miles the revs start to limit to 4000 and reduce to about 3200. This makes driving tricky especially when overtaking. changed timing belt,pully,fuel filter,c


I'm not familiar with your Hyundai, but the symptoms could be several things, I am thinking 1 in particular. Change your coil pack. I think you have the single coil pack that runs all cylinders. They can break down inside and not create the 20,000 volts or so that you need consistently. When you get to running temps, the coil gets extremely hot and can start breaking down and losing it's power.

Initial start up the engine sounds like its running on 2 cylinders under powered intil the temp gauge reads normal ???? any body got the answer please


Cold starting misfires can often be caused by either tired high tension spark plug leads or ignition coil packs. If replacing leads, then replace with a full, new set. Coils can be changed individually, but it is often the case that if one has failed, then the others aren't far behind. Some cars have individual coil packs on each spark plug. Some cars have a single pack for all plugs and some have coil packs which may control two or more plugs.

To check for a misfire (ignition failure) follow these steps:

(Cold start) (Use a pair of insulated pliers)

1) Start the vehicle

2) When the vehicle starts misfiring, disconnect plug leads or coil pack connections one at a time. If the vehicle idles even more roughly, then that plug or pack should be considered fine.
Replug each connection before disconnecting the next one. Once you disconnect a plug lead or coil pack connection and find no difference in poor engine running, then you have likely found the offending cylinder. Check the spark plug condition, lead and/or coil condition and connections on that cylinder.

3) Replace components as necessary.

How do i change spark plugs?


If you have the Inline 6 cylinder engine, the plugs are on top of the engine under the airbox (the one that says Vortec 4200). The airbox is held down by several bolts, disconnect the large air inlet hose and small hose on right side. Once airbox is removed, the coil packs can be seen, remove one coil pack at a time by loosening the single bolt (this bolt stays on the pack), carefully pry the coil pack up. The spark plug will be visible in the well. Make sure to clean out the well before loosening spark plug. Make sure to use only AC Delco plugs.

Were is the Ignition coil


On a 3.0 liter engine the coil pack is located on the backside of the intake manifold. You will need to remove the air breather from the engine to see it. On a 3.3-3.8 liter engine the coil pack is located on the top side of engine to the right of the oil filler tube. Before you remove the coil check for ignition fire at the spark plugs with an inline tester for spark. Also check the plugs for fouling condition and replace if needed. hope this will help you!!!

Coil pack should in the front top of motor, with engine running remove one spark plug wire at a time from coil pack ( careful not to get shock ) they should all have spark, if one don't replace coil pack.

How to change a thermastat 1994 ford escort with a 1.9 engine


1.9L Engine

CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. Remove the air intake tube, crankcase breather and PCV hose.
  4. Remove the ignition coil pack and bracket.
  5. Remove the upper radiator hose.
  6. Remove the ignition coil pack bracket.
  7. Unfasten the heater hose inlet tube bracket bolt and remove the heater hose inlet tube from the thermostat housing.
  8. Remove the three thermostat housing attaching bolts, then remove the thermostat housing and gasket.

Ok odds are you just need a routine tune up. Plugs, fuel filter, air filter. Now this engine uses coil packs i think, so you wont have normal plug wires. The coil packs are individual and sit directly on the plugs. So it is possible you have a bad coil pack. These engines were known to have this problem in excess. So try the cheap fixes first. plugs, fuel filter...these two is the best two to try first.. The air filter wont cause a bad miss unless it is completely dobbed up. so just for your own good to change the air filter.Now if neither the plugs or fuel filter fixes this car try this. Each coil pack will have an individual plug on top of them. So listen closely to your engine. Unplug each coil pack one at a time, Now evry time you unhook a plug the engine should miss, so unplug one at a time, and if the engine does miss they are working properly. Now if you unhook one of these and there is no change in the idle of your engine, my friend you have found the problem. All you have to do if you find one that does not change the engine idle, you just go buy a coil pack and replace it. This should fix you right up
