1991 Mazda 626 Questions & Answers
What do I do now that my phyco ex girlfriend decided to pour sugar and coffee into my engine via the oil cap.
sugar is hydrocarbon same chemistry as oil and fuel so it will mix in the oil ( make it a bit thicker)
coffee may not dissolve but will be held in suspension in the oil to be removed by the filter
so basically the contamination will go through the pump into the filter to be removed
So at this stage talk to several accredited service shops but I am thinking that drain the sump, change the filter
run the engine until hot then change the oil and filter again
collect a sample of the oil in a glass jar and look for contamination in the oil--it should be the same new color oil with no visible bits floating around
Maybe a second run till hot then again change the oil and filter
after that a filter change at say 1500 miles or a week to make sure that the filter is not blocking up
I feel that because it has not been run long that a flushing process using the grade of oil recommended along with frequent filter changes will most probably be the cheapest way to fix along with moving well away from the ex
I have gas and spark. Why won't it start?
Hi Barry:
If you've checked and you have hot blue spark at the plugs then it has to be fuel or timing. Let's assume you havent done anything to change the timing.
That leaves fuel delivery. Check that the injectors are being triggered. Could be you have a faulty cps.
I have a 1991 Mazda 626 that wont start
Look at the top of the engine and locate the fuel rail on the injectors. There should be a Schrader valve on the rail. Take a small screwdriver or a nail and push in on the Schrader valve. Have the helper turn the key on and look for fuel pressure at the valve. If there was no Schrader on the rail, just loosen the fuel line for the same results. If there is no fuel expelled, check the fuel pump fuse and relay located in the relay box. If these are not faulty, the fuel pump has failed and is need of replacement.
