U need to make sure the pickup pump in the fuel tank holds pressure, the pump has a built in check valve and if it is defective it causes a hard start and or rough idle.

    Ok u are right, but the same test still applies, make sure the pump check valve holds pressure in the line. there may also be an additional check valve in the fuel line at the tank. U are describing air in the line from the way it runs/starts

3.2 t6 ranger cold start takes long


Most long cold starts are from the fuel returning to the tank. Check ball stuck and bleeds off. Next time, turn the key on and off 3 times. If it starts faster, that's the problem. Check ball is in the tank, part of the sending unit.. I would live with it. Costly fix.

97 7.3 diesel hard starting


This is a good engine but they need work from time to time. What is the outside temperature while you experience this hard start? If you plug in the block heater, does the engine start better? Is the engine light on or does it come on at times while you are driving? Hard starts can be related to several different issues. This engine isn't easy to work on unless you have an advanced scan-tool. You need to look at live data and run some tests. The more common failures are clogged fuel and air filter. Dirty ,worn, or defective fuel injectors, low fuel-line fuel pressure, poor oil quality or low oil level, worn or defective ICP sensor, low injection pump pressure, loose or leaking IPR valve, or low compression. These examples should help get you started. You may need to have the truck diagnosed so you know what direction to go in. If you need any additional information, please write back. Good luck.

Toyota lucida hard to start most times. occasionaly ok. 2.2 diesel. everything seems to work as should


in cold weather diesel gels up and sometimes causes a no start issue..a cetane fuel additive helps with this issue. if temps go below 20 degrees, add a quart per tankful of cetane to the fuel to help start on cold mornings. also diesels require more amperage to crank than gas engines do..thus a stronger battery is needed..

2001 vw golf gt tdi is struggling to start when cold and sometimes hot..when started it struggles 2 stay ticking over at 900 revs...what can i do??please help


golfs coldstart system works when you open door/shut door/put key in hole and turn on (in that order)if you delay puting belt on for longer than say 30 secs the coils go cold,hence poor starting.if engine labours after cold start try using (really)one gallon of petrol in tank to clean injectors.
british army put petrol (30%)in diesel tanks of challenger tanks in arctic
to stop fuel freezing.....most parts replacement jockeys in garages will say if you put diesel in tank it will have to flushed out.lot of bollocks.
trust me.have put petrol in by mistake loads of times,only get hot start
problems if you put in too much.

HAd the same problem turned out to be the fuel tank selector vlv not sealing off m/t tank on return line so when truck sat cold fuel would drain off injectors making me reprime injectors (airbound)

The check valve on the fuel line at the filter housing may be leaking back not maintaining pressure when the engine is not running.
